A typical workflow for me is opening Vim (MacVim to be precise), doing:
:NERDTree <bookmark>
then manually opening various subdirectories I want to use. Often it's the same set of directories I had open when I was last working on the project. I'm aware of the O
recursive-open command but if it's a large tree I then have to go and close a load of them to clear the screen up.
Is there any way of saving the ones that are open / the general 'state'?
