Prevent NERD Tree from opening buffer on start

Question

I'm using Janus for Vim customizations.

One thing that bothers me is that it opens NERD Tree in a separate buffer on start. I don't want to disable NERD Tree completely. Just want to not get it opened on start.

Is there a way without tweaking the internals of Janus?

Answer 1

Finally figured it out based on the Janus configuration mentioned by @romanl.

I had to add to ~/.vimrc.after

augroup AuNERDTreeCmd
  autocmd!
augroup end
