 The application is currently primarly designed for X11 but it can run on Wayland as well through XWayland, with some caveats because of Wayland limitations.
 
 # Usage
-Run `gsr-ui` and press `Left Alt+Z` to show/hide the UI. You can start the overlay UI at system startup by running `systemctl enable --now --user gpu-screen-recorder-ui`.
-There is also an option in the settings to enable/disable starting the program on system startup. This option only works on systems that use systemd.
-You have to manually add `gsr-ui` to system startup on systems that uses another init system.\
+You can start the overlay UI and make it start automatically on system startup by running `systemctl enable --now --user gpu-screen-recorder-ui`.
+Alternatively you can run `gsr-ui` and go into settings and enable start on system startup setting.\
+Press `Left Alt+Z` to show/hide the UI. Go into settings to view all of the different hotkeys configured.\
+If you use a non-systemd distro and want to start the UI on system startup then you have to manually add `gsr-ui` to your system startup script.\
 A program called `gsr-ui-cli` is also installed when installing this software. This can be used to remotely control the UI. Run `gsr-ui-cli --help` to list the available commands.
 
 # Installation
 If you are using an Arch Linux based distro then you can find gpu screen recorder ui on aur under the name gpu-screen-recorder-ui (`yay -S gpu-screen-recorder-ui`).\
 If you are running another distro then you can run `sudo ./install.sh`, but you need to manually install the dependencies, as described below.\
-You can also install gpu screen recorder (the gtk gui version) from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder). This flatpak includes both this UI and gpu-screen-recorder so no need to install that first.

+This program has to grab all keyboards and create a virtual keyboard (`gsr-ui virtual keyboard`) to make global hotkeys work on all Wayland compositors.\
+This might cause issues for you if you use keyboard remapping software. To workaround this you can go into settings and select "Only grab virtual devices".\
+If you use keyboard remapping software such as keyd then make sure to make it ignore "gsr-ui virtual keyboard" (dec0:5eba device id), otherwise your keyboard can get locked
+as gpu screen recorder tries to grab keys and keyd grabs gpu screen recorder, leading to a lock.\
+If you are stuck in such a lock where you cant press and keyboard keys you can press (left) ctrl+shift+alt+esc to close gpu screen recorder and remove it from system startup.

 Show an error that prime run will be disabled when using desktop portal capture option. This can cause issues as the user may have selected a video codec option that isn't available on their iGPU but is available on the prime-run dGPU.
 
-Is it possible to configure hotkey and the new hotkey to get triggered immediately?
-
 For keyboards that report supporting mice the keyboard grab will be delayed until any key has been pressed (and then released), see: https://github.com/dec05eba/gpu-screen-recorder-issues/issues/97
     See if there is any way around this.
 
-Instead of installing gsr-global-hotkeys in flatpak use kms-server-proxy to launch gsr-global-hotkeys inside the flatpak with root, just like gsr-kms-server. This removes the need to update gsr-global-hotkeys everytime there is an update.
-
 Check if "modprobe uinput" is needed on some systems (old fedora?).
 
 Add recording timer to see duration of recording/streaming.
 
 Make folder with window name work when using gamescope. Gamescope runs x11 itself so to get the window name inside that we have to connect to the gamescope X11 server (DISPLAY=:1 on x11 and DISPLAY=:2 on wayland, but not always).
+    Detect if the window is gamescope automatically (WM_CLASS = "gamescope") and get the x11 display automatically and connect to it to get the application its running.
+    This seems to only be an issue on wayland? the window title of the gamescope/steam bigpicture mode is the title of the game on x11, so it works automatically on x11.

+Use x11 shm instead of XGetImage (https://stackoverflow.com/questions/43442675/how-to-use-xshmgetimage-and-xshmputimage).
 
+Add a hotkey to record/stream/replay region.
+
+Do xi grab for keys as well. Otherwise the ui cant be used for keyboard input if a program has grabbed the keyboard, and there could possibly be a game that grabs the keyboard as well.

+Make inactive buttons gray (in dropdown boxes and in the front page with save, etc when replay is not running).
+
+Add option to do screen-direct recording. But make it clear that it should not be used, except for gsync on x11 nvidia.

+Add window capture option (for x11).

+Add systray for recording status.

+Add a desktop icon when gsr-ui has a window mode option (which should be the default launch option).
+
+Use /dev/input/eventN (or /dev/hidrawN) instead of /dev/input/jsN for joystick input.
+
+Verify if cursor tracker monitor name is always correct. It uses the wayland monitor name for recording, but gpu screen recorder uses a custom name created from the drm connector name.
+
+Notification with the focused monitor (with CursorTrackerWayland) assumes that the x11 monitor name is the same as the drm monitor name. Same for find_monitor_by_name.
+
+If CursorTrackerWayland fails then fallback to getting focused monitor by window creation trick. Need to take into consideration prime laptop with dGPU that controls external monitors which cant be captured (different /dev/dri/card device).
+    Maybe automatically switch to recording with the device that controls the monitor.
+    In that case also add all monitors available to capture in the capture list and automatically choose the gpu that controls the monitor.
+
+Support cjk font. Use fc-match to find the location of the font. This also works in flatpak, in which case the fonts are in /run/host/..., where it lists system fonts.

+  <description summary="Protocol to describe output regions">
+    This protocol aims at describing outputs in a way which is more in line
+    with the concept of an output on desktop oriented systems.
+
+    Some information are more specific to the concept of an output for
+    a desktop oriented system and may not make sense in other applications,
+    such as IVI systems for example.
+
+    Typically, the global compositor space on a desktop system is made of
+    a contiguous or overlapping set of rectangular regions.
+
+    The logical_position and logical_size events defined in this protocol
+    might provide information identical to their counterparts already
+    available from wl_output, in which case the information provided by this
+    protocol should be preferred to their equivalent in wl_output. The goal is
+    to move the desktop specific concepts (such as output location within the
+    global compositor space, etc.) out of the core wl_output protocol.
+
+    Warning! The protocol described in this file is experimental and
+    backward incompatible changes may be made. Backward compatible
+    changes may be added together with the corresponding interface
+    version bump.
+    Backward incompatible changes are done by bumping the version
+    number in the protocol and interface names and resetting the
+    interface version. Once the protocol is to be declared stable,
+    the 'z' prefix and the version number in the protocol and
+    interface names are removed and the interface version number is
+    reset.

+
+	Most regular Wayland clients should not pay attention to the
+	logical size and would rather rely on xdg_shell interfaces.
+
+	Some clients such as Xwayland, however, need this to configure
+	their surfaces in the global compositor space as the compositor
+	may apply a different scale from what is advertised by the output
+	scaling property (to achieve fractional scaling, for example).
+
+	For example, for a wl_output mode 3840×2160 and a scale factor 2:
+
+	- A compositor not scaling the monitor viewport in its compositing space
+	  will advertise a logical size of 3840×2160,
+
+	- A compositor scaling the monitor viewport with scale factor 2 will
+	  advertise a logical size of 1920×1080,
+
+	- A compositor scaling the monitor viewport using a fractional scale of
+	  1.5 will advertise a logical size of 2560×1440.
+
+	For example, for a wl_output mode 1920×1080 and a 90 degree rotation,
+	the compositor will advertise a logical size of 1080x1920.
+
+	The logical_size event is sent after creating an xdg_output
+	(see xdg_output_manager.get_xdg_output) and whenever the logical
+	size of the output changes, either as a result of a change in the
+	applied scale or because of a change in the corresponding output
+	mode(see wl_output.mode) or transform (see wl_output.transform).
