Is there a setting so the navigation tree never scrolls horizontally, whatever the length of the name of the selected folder is?
For exemple, if I open a folder with a very long name by clicking it in the right panel (Explorer style view), the folder in the tree becomes highlighted (this is what I want) but the trees also scrolls horizontally. I would like the tree to always stay left, no scrolling, so I can always see the beginning of the folder name in it.
Thanks in advance!
I just realize that what I ask is not always a good idea.
What I would like though, is that the tree stays at the complete left if the beginning of the folder name can be visible that way, and scroll to the beginning of the name, if it's required to see that name.
Currently, if the tree has already scrolled horizontally and you select a folder that would be visible without any horizontal scrolling at all, the tree only scrolls to the beginning of that folder. I would prefere the tree to scroll to the complete left in that case.
I'm not sure if what I say is clear! 
You can lock the tree using the icon next to its close button. Then it won't change automatically at all (But that includes not following directory changes at all ...)
As far as I know there isn't currently a way to stop the tree scrolling right while still tracking changes.
Thanks Christiaan.
