Weekly development report: 2020/06/27

The development version: current almost "never-ending" saga named replace GTK with Tk slowly continues:

• Finished work on boarding UI, thus the combat UI is now done. Or at least its first, "the Ugly" version.
• In-game help also now works
• Added keyboard shortcuts for ship movement
• Started work on ship info UI
• Fixed a few newly created bugs and probably added a lot more for balance :)
