I was unable to work during the last few weeks because of University exams, now they are now finished. However I did do some work, submitting some small patches before the start of the coding period that:
- Changed the Gtk.Window, to Gtk.ApplicationWindow
- Changed the application to extend Gtk.Application
- Moved the main method to a separate file
Depending on the feedback from my mentor, I will probably continue updating the UI, this is somewhat matching my proposal, but instead of the number picker popup, there is now a separate entry location to the top right.
