Creating a borderless desktop application with osu.Framework

[just-ero]

Hello everyone. I have a bit of an odd question.

I want to create a cross-platform desktop app, a stopwatch. The window should be borderless (not fullscreen) and the user needs to be able to drag it around when they click anywhere.

Is something like this supported in osu.Framework? Would I have to call native APIs to make the borderless and dragging features work?
Would I be better off simply using a proper desktop framework like Avalonia or Uno?

Customizing window style/decoration is not supported as of yet, although adding support should be straightforward as it would just consist of hooking up SDL2Window/SDL3Window to call SDL_SetWindowBordered. If you're interested, you can delve deep into the codebase and add the feature yourself.
