i'm not a fan of the UX or how it feels, but i can write notes all i want and add "keywords" or "tags" that i can search for and go through. todos, dates, important things, brainstorming, drafts, etc.
for example, for a book project, i'll write the word "preacher" at the top and then write some words that were in my brain. then i'll have 100 notes with the word "preacher" that i can search for and go through when i need to draft the idea. i can combine tags too, like adding "denny" to "preacher".
or for a work project, write the name of the project as the tag, some todos, meeting notes, design docs, resources, etc
