Right now a single font size is used throughout for both the bottom bar & UI buttons. In addition this same font size controls the sizing of text in the pin detail overlay. The preference that controls this is fontsize_ui.

Perhaps there should be a few different preferences:

• fontsize_buttons
• fontsize_bottombar
• fontsize_pinoverlay

From a UI/UX perspective, three finger rotate increases/decreases this font size. The above 3 preferences could be implemented while also keeping the end-UX the same (e.g. just chaining prefinc commands); but perhaps by default 3-finger rotate should adjust UI buttons.. while 4 finger rotate could adjust pin detail overlay (and maybe bottom bar sizing).
