This one is basic...
I spent quite a long time configuring a whole new line for a popup... setting colour ranges, positions, fonts, all stats, you name it. Then last thing I wanted to erase one stat and missclicked erasing the whole line! Couldn't find the undo (or ctrl-z). Only way is to do the whole thing all over again?
About the copy paste I've said, if I want to use this same line on a different popup on a different HUD profile... there is no way I can do it, right? Only exporting the whole popup, but there is no copying a single line in it.
