I have an idea for a design. It's about the implementation of the Ribbon UI into the editor (for those who don't know, that's the interface of Microsoft Office apps). For example, this is GDevelop, a program to make cross-platform games:
Can you see it? It looks good.
Now they're working in a simplified GUI for the fifth edition of GDevelop, it's even simplier now. I don't know if our editor can get to this simple, but I find it as a good inspiration.
The current GUI is nice, looks good and is easy to use, but I always wondered how can we make it look more modern.
