But recently they decided to get rid of GTK+ and use the tool from the "other end", the gorgeous Qt :) (which is still at beta stage). And to be honest, I don't know if the adaptation of Qt4 has anything to do with it, but heck, emesene looking soooo much better!.
*. The Qt4 "skin" is disabled by default (still under testing). But lucking you can still forcefully enable it by using the command "-e main:qt4_main".
*. Simple interface which is easy to get used to.
*. Simple text editor.
*. Add emoticons, can't live without them, let me put one here :).
*. Enhanced group chatting.
*. Easily switch between tabs using "Ctr + Tab" keyboard shortcut.
*. More translations supported added.
*. A lot of bug fixes are just a few to mention.
So as I said before, if you use Ubuntu 11.04 Natty Narwhal and want to install emesene, then open your Terminal and enter the below command.
sudo add-apt-repository ppa:emesene-team/emesene-stable
sudo apt-get update
sudo apt-get install emesene
