In options you have the selection to turn on the file tabs. Right below that are buttons for "Colors" and "Fonts". I don't find any way to change the color of the active file tab and that would be helpful. My old eyes can't distinguish the difference between the active tab and inactive tabs. I would like to change the color for the active tab, both above the drawing on the list if open files and in the project manager list of drawings, to something bright like green so I can easily see which one I am working on.
