Hi Alexey ,

Some other feedback from me :)

1. It seems like a multi-delete option for the long list of messages is needed.
This  may also work for the search results of the message list.

2. Also a search function inside a specific dialog could be nice. There may be pages of text in a certain dialog and sometimes we need to find a certain part.

3. Message forwarding is a nice feature and will be functional. Let's say I have a personal profile and an adminsitration profile for the messages that comes to the administation profile I need to change the profile or if it's another account need to login with that account. If there is a forwarding option it will be very handy.

4. Named participant groups, like in WhatsApp will be great also.
