Can't read behind node labels

Possibly related... I'll let you move this issue if it is.

Currently the node labels are black text on an opaque white background.

Describe the solution you'd like

• Allow node labels' background transparent, so we can see nodes that might exist behind it.
• [optional] Alternatively, allow the entire label have a set opacity (default 100%)
• Hotkey (']' maybe?) that when depressed, will make labels opaque. Alternatively maybe this just hides all the labels?
• Setting that changes the hotkey behaviour between press-and-hold (default) and toggle
