Imagine you have two directories which aren't that near in the tree (so
not just a simple "up" or something like that away) and you need to
change between this directories often (for example you have a project's
source directory and a public_html folder or something like that).
Without tree-follows-view you have to expand the corresponding nodes
yourself of both directories yourself. With tree-follows-view you just
change once to the other directory and both directories will be visible
on the tree where you can switch between them relative quickly. Sure,
you could use symlinks but perhaps you don't want it like that.

BTW I personally would perhaps vote for a combination (1 + bookmarks
toolbar) as the bookmarks toolbar is like an additional feature, it
doesn't need to change the tree-follows-view behaviour.
What's your opinion?

I'll probably try that in the next days.
