Aqua-Soft ForumsOne of the things Aqua on the Mac has that Windows doesn't have is support for per-pixel alpha blending. That is, being able to have buttons and Start menus and that kind of thing that blend into what's behind them so that they're really smooth.
WindowBlinds 4.5 is newly released this past week and with it, skinners can create visual styles that have per pixel alpha blending pretty much everywhere. The only thing left are the actual window borders (title bar and such) which is being worked out but it's a performance issue (i.e. moving windows, resizing them, etc. even on a Mac where it's built in isn't exactly lightning speed -- that's what we have to overcome).
Below is a look over what's special about WindowBlinds 4.5.
