Suggestion: Make this plugin compatible with fzf and similar.

I noticed the Ctrl+J/Ctrl+k keybindings stopped working on fzf after I had this plugin installed. I added fzf to the is_vim regex and it fixed the issue.

So I'm wondering: Would it be a good idea to add such exceptions to this plugin?

Sure! Feel free to open a PR (not the is_vim check is defined in two places, the second being the TPM plugin file).
