Edit Guide colors and position values in the Glyph (guides) screen
The 'system guide' lines are too dim even when transparency is turned off. I'd like to be able to select my own guide colors on the Glyph Edit screen, by clicking on the orange color blocks. A pop-up color selector box would be perfect. Keep the transparency adjustment.
Also, make the guide position values adjustable on that screen, because I can see the glyph while adjusting (for a new font).
