A standard enough feature for most code editors, would it be tricky to add this to the CodeEditorComponent?
Yes, it’d be quite tricky - the reason the code editor is so fast with big files is because it doesn’t have to deal with stuff like that.
(Personally, I couldn’t bear to edit code with line-wrap enabled… Do some people really do that!?)
I say standard enough feature, but it’s not one I’ve ever used 
if it’s not a straight forward then I see little point in wasting time on it. Cheers.
I use it. Saves scrolling around when it’s just a few lines, or if I shrink the width of the code editor temporarily.
