I was testing out a few variations of JVM Arguments to try and reduce the crippling framerate lag that I've been seeing in 1.8.2. I used a much longer series of arguments than before and when I went back in to change it again the Profile Editor had expanded to the full length of the argument text string. I'd expect this to be a dropdown / popup / or scrolling type of a menu so that this doesn't occur, as it makes the Open Game Dir and Save Profile buttons off screen.

Here's the text string I used (work in progress but you get the idea as far as the length):
