I just installed 13.04 from (12.10) graphics are great except the dropdown folder feature is gone.There was no preview about what changes there are and I thought is was a software update..like of the ones that appear when opening firefox. now there is now feature in the help menu for new features. I also cannot find anything online. Help, I am afraid I SHOULD NOT have installed the upgrade.
