 ## Inspiration
 
 This plugin is heavily inspired by the functionality in the Vimux plugin. This
 plugin aims to implement a similar feature set while not requiring Vim with
 ruby requirement. In addition a few new commands not found in Vimux have been
 added to provide additional control over the tmux runner pane.
