Is possible tree to stay?

[schferk]

Is it possible to have the tree stay in its normal form when I open a subtree in any other tab? I would like to expand the subtree, but not the tree in the first tab, so that this tree can serve as a table of contents of my big subjects. But whenever I expand the subtree in the other tab, the subtree in the first pane is expanded with. If this is not possible to prevent, would it not be a good idea to have this in Ultra Recall?
