* The back end could be improved, it looks clunky, not user-friendly.
* They need a desktop agent/tool or something so that when someone calls me from a website widget/embed, it will ring my desktop. I find it impractical to have to remember to sign in every day and leave my browser logged in the whole day just incase someone calls me 1 time out of the month.
* Mouse movement have a 2-3 second delay. So there are some lag.

I've tested on myself and screen share works fine, I plan on using this for meeting with clients mostly. I don't particularly like zoom.

Feel free to use my critiques as feature requests if 11sight is reading this. Thanks.
