Feature request: Sidebar module and Avatars in mobile interface

I saw it somewhere - Make a "module" on the sidebar with the latest 10 (or about 10) users but only with avatars uploaded. This will make Jisko one step more like community. This module can be called: Let say hello to:

It will be good if in mobile version - infront of every username to have a small pic/avatar of the user. I think it won't eat much traffic because almost everywhere has WiFi net. Also much phones have cache on their browsers!
