Narrow region plugin slows down leader command for NERDTree

[DanS]

I'm not sure what changed but a while ago opening/closing NERDTree with <leader>n became much slower.

Yesterday I tracked this down. The narrow region plugin defines a leader command <leader>nr. When that isn't there Vim can react to the <leader>n command as soon as the "n" is typed. With the narrow region command there Vim waits a while after <leader>n is typed to see if you will type an "r".

I've started avoiding this issue by adding:
nunmap <leader>nr
to my gvimrc.after. This works for me because I use <leader>n all the time, and I never use <leader>nr.

I think Janus could be improved by providing a solution to this "out of the box" so that the NERDTree <leader>n command responds without delay. My suggestion would be to map 'narrow region' to a leader command that does not start with 'n'.

Do you want me to create a PR for that? :)

Sure, what mapping you propose for narrow region?

[dolohow]

Maybe <leader>mr?

[kalbasit]

or <leader>rn perhaps ?

[dolohow]

Ok, then ;)
