Besides allowing me to customize practically the entire interface, it has full markdown support and I can version my documents wherever I want! Fantastic, lightweight and free!

Use as a personal knowledge base and organization of ideas. It's almost perfect, it's because it's slow at certain moments and because it consumes a lot of battery on mobile devices (as in the case of the iPhone, for example).
I've been using it for many years and I love all the features, especially how it works in terms of the recurrence of tasks and the use of natural language.
