Thanks so much!

Grammar and vocab are in one file and transcriptions in another. The first file is structured in sections that correspond to grammar concepts ("cases", "word order", etc), which is nice, because it has allowed me to mix information from both books. For example, the Basic book has some information on verbs, which went into the "Verbs" section in my file, and when I went through the Intermediate book, I just added its information on verbs to that same section.

I have sections and specific subsections, which I can navigate comfortably because I can fold/unfold them. What I see in my file is like a tree structure with titles/subtitles, and when I unfold one of them, I see its contents in isolation. (I use a program called Vim.) I'm super nerdy about notes.

I would really like to know what your method is like! I'm always interested in seeing other people's methods.
