 # To do
 
-## Quality of life:
-
 - [ ] Document creating new applications, e.g., as in [Asana for Linux](https://git.nunosempere.com/NunoSempere/asana-for-linux)
-- [ ] Use something other than Whatsapp as an example syslink.
+  - [ ] This time, use something other than Whatsapp as an example syslink.
 - [ ] Fix bug about distorted audio. Maybe related to [this pipewire issue](<https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1547>)?
   - See whether it even exists at all
-- [ ] Fix PageUp/PageDown shortcuts.
 - [ ] Upgrade to GTK-4 / Webkitgtk 6.0? Will take a fair amount of time, since GTK4 redesigns the application model somewhat.
   - Instructions for webkit-6.0 [here](https://github.com/WebKit/WebKit/blob/ed1422596dce5ff012e64a38faf402ac1674fc7e/Source/WebKit/gtk/migrating-to-webkitgtk-6.0.md)
