This addresses the shortcomings of the cumbersome "choose image" feature by expanding to an "always open" palette.

It would build off of "shape tools" but it would be the ability to have a constant menu of "shapes" open in a "drag and drop/resize" format. This could mean many different kinds of menus... like greek/math-syntax, map symbols, etc.

I can absolutely say that the appeal for technical disciplines would go up dramatically from its already high level... if you had the ability make or download menus of various kinds of symbols.
