Make directories with Vim Eunuch
Vim Eunuch has been my go-to Vim plugin this week.
The :Mkdir command is awesome. It's the mkdir you know and love, inside Vim. I find it useful when building a set of Rails views for a brand new controller. No more shelling out to make a directory, just to write my file.
:Mkdir! is even better because it adds the -p flag, creating all intermediate directories as well.
