How can I adjust the transparency of the top panel?
Well .. the question is as simple as the title.
But for details .. I really like the look of the task bar when I start ubuntu when I choose from users accounts .. it is simple and has a little transparency .. I want to have these effects on my task bar all the time.
How can I change the opacity and the color of the task bar ? Is it themes ?! How can I find trusted ones and how to install them ?!
