Customize Token Bar/Circle Names, not just color

I see the ability to change the token bar colors + display settings for the three bars/circles, but I not see a way to rename it from "Bar 1" to something more game system specific (Toughness, or whatever). It seems to me this suggestion would be easy to implement, but I'm unsure if it's a feature restricted to mentors or something.

That's a good suggestion. You know that you can set the bar to be associated to Toughness, of course, right. But I see the limitation you're talking about that you cannot actually change the word "Bar 1" in the token popup interface. So you can change the meaning of Bar 1, but not the label "Bar 1", and this suggestion would allow you to edit that text.

Here is a more complicated Suggestion that you might also be interested in commenting or voting +1, since this custom-HUD suggestion could be used for what you're saying,

Yes, my suggestion is exactly as you say. And that other suggestion you linked to looks cool for sure.

Hey folks, vote me up gosh darn it! lol
