Suggestion: Opaque Titlebar
Lovely program here. Though I'm wondering how keeping the titlebar of a seethrough'd window opaque optionally would fare? Would make moving It and making It active again more convenient.
Really good idea that would need some investigation. Curently, we simply look for "top level" windows, which can then only be made transparent completely - not partly. Technically, It should be possitble to just transparenticize (?) the client area - i.e. the part without the title bar. But that will require closer inspection of the window's composition, which a) might not be possible and b) could lead to problems with non-standard windows.
But we're keeping it on the list as a good idea!
