Improve overall speed

[spenweb]

I have noticed a significant loading time increase after installing this plugin. Also, have noticed Nerd Tree takes a significant amount of time to open as well after installing this plugin. I have yet to jump into the vim scripting language, but if anyone has any ideas as to how to improve the overall plugin's speed (maybe by making it async if it is not already), please let me know and I may be able to make a PR to support this awesome plugin 😆

Side note: This plugin rocks!
