@Dimster You are trying to color code the stage of your program edits??? Yikes!
Do you know now with QB64 v2.0+, when you Open a 2nd and 3rd QB64 window the screens will be different colors, or can be, and dang if I remember how I set it up but I have my 2nd window set to QB64 Red.
Oh! just set the Color Scheme when you have the 2nd Window Open.
I use QB64 Red for Read Only :) Now if I open a 2nd QB64 IDE, I see it immediately and now know which is the one I want to edit.
BTW XmasSnow sucks because if current line is like a For of an IF it will be Red-lined until you "fix" it with the Next or the End If, that's fine but when something is Red-lined and all the print is dark, you can't read the line!
