I developed a personal and fully custom My Anime List Style which I then made for public use and can be downloaded here: github.com/RafaelDeJongh/MyAnimeList
This is a minimalistic flat designed List Style which focuses around showing the Anime's cover in a nice grid like structure.
A live example can be viewed here: myanimelist.net/animelist/RafaelDeJongh
Besides this I've also developed a script to be used alongside the website, where the user is able to quickly create and add various custom tags.
You can download and make use of this script with browser plugins like Tampermonkey: github.com/RafaelDeJongh/MAL-Faster-Tag-Adding
