I think the title says it all.
It looks great as it is so concentrate on security features not making it look all fancy and making more vulnerabilities.
Get rid of that logo and let people put there own in because I see that come up a lot.
Make a right-click admin panel on each user for volume and cam, block, kick and so on.
Take away registering by email and use the bitcoin method to make a wallet with 6 rememberable words to get your password back, easy and simple.
make sure there are never any peer2peer leaks add a nice profile to each user so the can give stats about themselves
make plugins if its to hard to code some options that the owner can install.
Give the server owner a Great Admin control panel, then you can really put some great options on to protect rooms from trollers playing porn in the room full of kids ( yes I have seen it on YouTubes)
Most of all just copy the same method Facebook uses to block people, one banned the troller can not see the room ever again with IP ban too.
I use to use automated IP ban into the firewall on my projects because if you also ban proxy use then if they make a new name to come back they still can’t see the room and public proxies are too weak for WebRTC.
Also, make the rooms invisible for owners.
encrypt the passwords.
