Demetra #5231 introduced a feature that annoys me greatly.
That 'excluded from compilation' stripe poping up at the top of the editor window and disappearing on every edit causes text jump up and down all the time. :(
You should either make it more 'stable' - show immediately when file is opened and do not hide when it's edited and saved or make its appearing do not shift the text on the screen or remove it completely (isn't a cross on the icon not enough?).
And while you're polishing this feature is there any way I can turn it off now?
