HI,
1. Ok, It will be great to change it on parameters 
if developpers hear me 
2. Great ! I follow this, now my customers don't have to add someone and so they see the status directly. Another good news : Il display automaticcaly Full name of the contacts
3. Not Great 
I hope that someone will work on it soon (i'm not devlopper so i can't do anything). Also a shared screen mode can be cool.
Thanks for your reply.
