Maybe I'm annoying but transparency: Copy is still not working correctly on linux and the problem with tooltips about I was writing here:
http://www.rainlendar.net/cms/index.php?option=com_kunena&Itemid=36&func=view&id=5283&catid=7#5283 is still not fixed too.
If You fix this two errors this would be for me the top of happines

.
About transparency problem: Maybe try do transparency copy like the Conky application is doing it. It's working all day with refreshing every 2 seconds and there is no such problems like with rainlendar.
And about this tooltips... only I have this problem...? I was updating the system, drivers, gnome libraries, X server and nothing helped :/
