http://ubuntuforums.org – hi!, I just try ubuntu 12.04, everything look neet and awesome! There is only one big problem that i need to fix for myself. The grab handle slider thing go over thoses very usefull expand triangular icon witch is so annoying. exemple I would really like to remove/hide these. anyway they are totally useless when you have a scroll wheel on your mouse! you really need to be presice to not trigger the slider! too much for me! thx a lot!
