Requested Limit browsing and change window's color

[Idjo]

Hi, I have 2 Requests:

Please add an option to limit the extentions that open while browsing a directory. When I'm browsing I don't want to see TXT, audio nor video files.

Please add a keyboard shortcut to change the window's color. It is needed frequently while handeling images with transparency.

The first request is already available.

Properties, Extensions, Load custom file types.

Thank you.
