Here you can find a curated list of tools and websites I strongly recommend for any film editor and filmmaker. I have tested almost every recommendation on this page. Many of the resources listed here are what I use on a daily basis.
Disclosure: some of the links below are affiliate links. Please understand that I have experience with these companies, and I recommend them because they are helpful and useful, not because of the small commissions I make if you decide to buy something. Please do not spend any money on these products unless you feel you need them or that they will help you achieve your goals.
Nitrate from FilmConvert is the best color plugin I've ever used. I started using it last year and now I'll drop it on the timeline for each project I'm working on. The promo code 'CUTTOTHEPOINT' will give you 10% off.
