Better menu style for colormaps/colors

[pllim]

When I have useMatplotlibColormaps = True set in my ~/.ginga/general.cfg, I find that I have to scroll all the way down for some of the colormaps, which are arranged in alphabetical order. This can feel like it is taking forever to switch colormaps sometimes, especially when I have an "a" and I want to use a "z", or something like that.

It would be nice to have alphabets listed as the first menu, and then only the colormaps that start with that alphabet in the sub-menu. Or some kind of short cut to jump to the desired alphabet.

This also applies to the color menu, i.e., when I have a combobox to let user select a color for the shape or whatever.

Here is a screenshot to showcase my misery of scrolling too much:

I feel your pain. I think the plugin lists are long and getting longer as well. Maybe time to look at nested menus? I'm ok with categorizing them in some fashion.
