 # 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)

 # Previously done
 
+- [x] Fix PageUp/PageDown shortcuts.
 - ~~[ ] Set [`webkit_web_context_set_sandbox_enabled`](<https://webkitgtk.org/reference/webkit2gtk/2.36.8/WebKitWebContext.html#webkit-web-context-set-sandbox-enabled>), as recommended [here](<https://blogs.gnome.org/mcatanzaro/2022/11/04/stop-using-qtwebkit/>)~~. Irrelevant with upgrade to libsoup3.
 - [x] Update to webkit2gtk-4.1
   - [x] Change README and point to last Ubuntu 20.04 commit
