It would be quite useful to be able to add color coding to the person edit window. For example, if you do a “Find everywhere”, you can select the person, but not easily tag that person for followup. Yes, you can use groups, but that is less convenient. The color is stored as an attribute of the person, so it shouldn’t be that difficult to do.
Totally agree with this one. There seems to be a lot you can do to the person outside of the person edit window that should be there - but especially color coding.
