When a window is "custom chromed" and has no window-icon, it would be nice if Groupy would get an icon for the window from the app / process / taskbar icon...
For example.. Spotify, which is a pretty darn common app... has no window icon... so groupy doesn't show one, but it does have an applicaiton/taskbar icon.
Here is a screenshot of a spotify window in groupy with no tab icon...
