No no, far from it. A trivial matter, and hardly worth the bother. I just thought it might have actually been a bug.How "grey" it becomes is set by your GTK theme and thats outside Geanys control, but you can customise it with Menu->Tools->Configuration Files->geany.css" (if it _really_ matters, you would have to learn GTK CSS;-)
Oh, and I did my homework :-)As the proverb said "Give a man a regex and you feed him for a day, teach him to regex and you feed him for life" ... or something like that ;-)
I was just about to say exactly that in almost exactly the same words -- beat me to it.
