Lock the tree so it doesnt move when switching windows

The top of the visible tree is changed to the current used tab

Imagine two windows in the tree, when I click on the second (any tab within it),

I can't see the first window anymore

I wish to have a tree that DOES NOT MOVE

so that I can see the entire tree all the time (only with small trees obviously)

When the trees are too long to be displayed in one page, you could do different things:

- you don't move the tree at all, unless the users moves it

- you move to the current tab in the tree but not at the top. The thing is that if you could technically see the two pages in the tabs, you should do it ( it's not really important)
