Thank you for the warm welcome and the lenghty answers to my post. I will read through the links today, and maybe I was just not using things correctly in some cases.
The Problem with the left Sidebar is, that I have to scroll up and down the whole time. If all are collapsed, then its perfect. If I click on a sidepanel Tab I would like to have the things displayed in the center instead of below the sidepanel Tab.
Well, going to read the links now
.
Thanks a lot for the replies, the help and the links.
