Thank you for an answer!
Yes, i already noticed that thing that you've said about windows frames, that made me think that Windows 7 markup was made by blind monkeys in a dark room
Another issue that comes up a lot is when making images in photoshop and them importing them into wsb they are not always being ported into the app just as it looked in photoshop they have an app to try and correct some of those issues called Alpha Converter that you can use to import the images into wsb so u can correct those issues.
Where can i get this Alpha converter? Or you mean that it's built-in wsb already?

I'm concerned mainly about the color problems, for example 10% alpha white actually become 10% grey after applying theme...Which make it almost impossible to edit complex white shapes...
There are no universal workaround about color correction?
As i understand, wsb convert .png into .bmp with alpha channel?
If so, than in this process there must be some color-sheme shift or ICC corrections...
