it's quite irritating. i've turned labels on because i got a big new display and have room to spare, but none of my buttons are the same size. is there a way to change this?
You could make them all three-buttons and put something with a long-ish label on the middle-click action of everything so they all take on the width of that (assuming it's as long or longer than the other labels).
Three-buttons will be as wide as their widest left/right/middle sub-button.
