I installed Sublime Text 2 on 12.04 as per this tutorial.
However I don't have adequate permissions when launching the program from the Unity launcher. For example I cannot install packages, or if I add a folder to the sidebar when I close Sublime and reopen, the folder is no longer listed. If I run sudo sublime in the terminal all changes remain after closing.
I've tried chown-ing the Sublime Text 2 folder in usr/lib
sudo chown -R mylogin:mylogin /usr/lib/"Sublime Text 2" but this seemed to have no effect.
