It would be awesome if tmuxp had an ls command (tmux has one) that will list the user directory's yml/json files.
Also, ln for a quick way of symlinking project's .tmuxp.yml files into the user directory,
For example, list, link, and load stored workspaces:
$ tmuxp ls
acme.yml
foo-api.yml
$ cd bar/admin
$ tmuxp ln -s . bar-admin
$ tmuxp ls
acme.yml
foo-api.yml
bar-admin.yml
$ tmuxp load -y foo-api
