Are you annoyed with the Sidebar taking too much space?
Solution:
use keyboard shortcuts to open/close:
to open use <ctrl><4>
to close use <ctrl><0>
you can use <ctrl><F7> for a menu with open panels:
You can then use the keyboard to select a panel (let’s say Sametime), you then use some <tab> keys to navigate to the searchfield and you can easily find your desired chat partner without the need to use the mouse
