- a nicer contacts view, grouped by the first letter
- push-to-talk
- call actions
- set/change/clear password
- rename call
- share call
- and many more options that I leave to you to explore!
- support for joining public calls (both WITH and WITHOUT the password)

And, of course, various other small fixes and improvements.
