[updated]

I have attached a rough sketch of the proposed layout. I did use something similar to it before. The users liked it since the full size avatar of whoever last chatted would show up.

Thanks.

----------------------
I am totally lost. Can do you do a sketch in pain or kinda like that ?

Feature request: I would like to see an alternative avatar layout where only the last person who chatted could have a full avatar showing. Nobody else's avatar would show. I used to have a program that did this, but I like yours better overall. That feature would be nice since as you chat the avatar of the last person changes and you can see the detail from their avatar in full size without taking up screen space showing everyone's avatar at that size.

The format then would go like this:

Column 1:
First rows: Enter Chat Here - Buttons - Icons
Last rows: Last Person Chatted Avatar (Full Size Avatar shows)

Column 2+:
As it is now, Date, Time, Chat, etc.
