First off, fantastic site and great initiative! This suggestion is more of a quality of life suggestion than anything else, but I'm sure there are many more players/gms like me who don't use Firefox/Chrome for a variety of reasons. Over the years I've gotten so used to my personalized settings in Opera, that switching to Chrome just for roll20 is unwieldy and awkward. If I can have a tab open with my roll20 campaign as well as my other tabs, that would be fantastic!
I'm hoping this can be taken into practise, and many users will thank you for it. :)
Again, much <3 for the site.
