Add an "About" screen
The app does not have an "About" screen.
An "About" screen can be helpful to see
- the installed version of the app. Currently, there is no way to determine the version of the app in a user-friendly way (using
apt
to identify the installed version shouldn't count😅 ). See also #263 - names of code contributors, or a general "GNOME developers" message
- links to contribute - A link to this Gitlab repo or a contributor doc can help with development.
