Screen space for private whisper channels

[bra1n]

Something I've been thinking about for a long time is that in a lot of our games a lot of people use the chat request feature to whisper each other, the issue with this is that it means everyone is put into the section at the bottom of the screen underneath the named rooms. The named rooms then never get used and is wasting space.
This then means anything underneath the chat channels is barely visible such as private messages and sometimes chat requests.

I've had a few times in which I'm not able to see a chat request because my screen isn't big enough and I've then got to go full screen.

A solution to this could be: When someone requests a private chat, it moves them automatically to an empty named chat room. If there are no empty rooms then have the extra whispers underneath.

I understand that part of the reason of having it so that people can't just randomly join whispers they're not invited to.

A second part of this which could be a feature even without fixing the above could be the ability to request to join a room/be invited into a room.

So lets say Me and Ben are in the Potion Shop and we both want Kat to come join us, either of us could press space, click on Kat and Kat would get an chat request for the Potion Shop.
Likewise, Kat could press Space, click on the Potion Shop and both me and Ben would get a chat request and either of us could accept it.
