More visible frame edges
Frame edges are too thin. Too hard to see. Please consider teachers teaching your product in class on a projector.
Even if there was a setting in Preferences for heavier frame edges.

PLEASE anyone, I have the same issue. It's RIDICULOUS to have light cyan lines against white, they are almost invisible. How is it that you canadjust so many colors for grids, etc. and there's no way to change the text edges and handles thickness or color!?
