Create a custom manager and migrate to nvim

I've migrated to Neovim because of one thing... Luke Smith-senpai...

Ever since I've seen him typed 'nvim' in his recent videos, I was devastated. All of those hours that my little heart and soul poured into creating a 130-line vimrc to configure Vim to its absolute in the way I wanted to use was gone. All of those 7 days and a few minutes every now and then, are crushed.

It is truly a betrayal to see it use a modernized version of a relic of the past. I first thought, "How dare he?". I was not able to sleep well the following days. It was heart-wrenching.

Out of spite, I've tried to. I've nothing left and you know there is a saying 'a weeb with nothing got nothing to lose'. All it took was to rename certain files, reinstall the plugin manager and its plugins, a grand total of 5 minutes. My heart skipped a beat.

It was like being a birb with broken wings trying to fly and eventually didn't left off until its talon is in the ground. And the ground is Neovim. Now I love Neovim more than ever... Thank you Luke Smith Unaboomer-kun-senpai. It was truly a wonderful experience.
