group header tweaks (feature request)

[transat]

Currently only the +/- sign on the right of group headers acts as a button to open or close the group but is there a chance to make the whole group header clickable instead? It would be useful for touch interfaces and would allow optional hiding of the +/- sign when appropriate (top level of a menu-bar).

Another feature requests to consider: replacing the panel header load/save icons with custom icons (maybe using fontawesome... which would allow to easily add icons to any other gui button?). The current icons look pretty bad on tall panel headers.

Sounds both reasonable.
About the second one: I will try to optionally include ofxFontAwesome and ofxFontStash to be able to make this prettier. I need this feature too.
