I did do a search for this, but only found a bug report where the person was complaining about the treebar covering windows. If I missed a previous report for this, I apologize.
What I would like to see, if possible, is the option to have the treebar show-up when you point to the left/right side (depending on where you have the treebar), temporarily showing over the windows, then auto-hiding again when then cursor is removed from the appropriate side. This is similar to the method that the Windows taskbar uses, when the properties for the taskbar are set for On Top and Auto-Hide (as indicated in Windows XP...the system I'm currently using, but I believe it's the same in Windows versions from 95 on)
If this isn't feasible, or possibly in addition to the above, perhaps a method of allowing a treestyle display from Window section in the menubar.
