I just recently started using XFCE 4.4. I was using 4.2 before. It's just awesome. Much better than anything else. Thank you for the great work.
I will thank them all too. I used 4.2. for a time but wasn't real satisfied and had used KDE since then. But the things I missed are included in 4.4.
The main improvements are:
Thunar is fast as Xfce and the only filemanager I need, eccept for Midnight Commander of cause. The old filemanager Xffm was slow and useless.
Quichlancher is another neccesary thing that I couldn't live whithout. The old Launcher wasn't fun at all.
With 4.4 I can't come up with one bad or missing thing right now, after that I used 4.3.99 and 4.4 as my only window environment for close to a mounth.
