Compability with Vimfiler
I really love this plugin, but the most and only part which makes me a bit sad is that it isn't compability with Vimfiler. :P
:VimFilerCurrentDir

after saving session and opening...

It would be so awesome if u could implement the compability with this plugin like the compability with NERDTree :D
In my opinion, the special handling of NERDTree etc. should be replaced with a generic extensible configuration. People would be encouraged to develop adapters for their favorite plugins on their own. They could still be submitted here for inclusion in the default plugin.
hmmm i c.... @xolox what do u think? :O
@take: I agree with @inkarkat in the sense that I won't simply add integration with Vimfiler to resolve this issue, instead I would like to set up something generic that can be used to define integration with arbitrary third party Vim plug-ins. I created xolox/vim-session#98 for this.
