vim-mr (mr) is a plugin to asynchronously record MRU (Most Recently Used files), MRW (Most Recently Written files), MRR (Most Recent git Repositories), or MRD (Most Recent Directories).
Use mr#mru#list(), mr#mrw#list(), mr#mrr#list(), or mr#mrd#list() to list MRU/MRW/MRR/MRD like:
:echo mr#mru#list()
:echo mr#mrw#list()
:echo mr#mrr#list()
:echo mr#mrd#list()
If you want to delete a filename from each list:
:call mr#mru#delete("foo.txt")
:call mr#mrw#delete("foo.txt")
:call mr#mrr#delete("foo.txt")
:call mr#mrd#delete("foo.txt")
The original idea of MRW comes from https://github.com/rbtnn/vim-mrw.
