As I mentioned in one of my previous posts (or maybe multiple ones), my note taking tool of choice is Joplin, because of its flexibility, customizability. I did quite a lot of customization on it, including some CSS styles for the UI of the program itself, and the rendered notes, to make things more visible, prettier, and also included workarounds for some rendering issues. I also like to use the plugin called Templates with a template I made to create study notes from.
I decided to share these things with you, maybe some of you will find them useful too.
