This may be something we do in the future. I'm not entirely sure, since the way browser add-ons are displayed have changed and I think you need to have installed Classic Theme Restorer or some other add-on bar extension in order to get add-ons to do that now. It's something I'd like to add, but it will probably take some time since I'm still learning.

We'll likely add some hover text so hovering over the add-on will tell you which account you're on, though.
