Pinning like sticky notes

@Andreas_Hegenberg Sticky notes can make its own windows float while minimizing them to just the title bar.

BTT is great at pinning windows from other apps. Would it be possible to add a feature so that only the title bar is visible?

Andreas: As I see it, it's already possible to pin a window in a “mini version” to a specific location on the screen.

But it looks like I have to adjust the size manually. Or am I missing something? Can you help please? Thanks!
