Feature request: Custom personal categories

I like importing my own text and using Readlang’s reader for study, but unless I’m missing something, I’m stuck with a limited organization by category. Is there a way to create my own personal categories? If not, I’d like to suggest this as a new feature for Readlang. I don’t think it would have merit to carry over to public texts. I think that would be a distracting complication.

Perhaps an implimentation of tags would be the easiest to add?

PS: while I’d love to contribute to the public library, the texts I study are transcripts of proprietary text I don’t have permission to share.

What is it about categories that you prefer them over shelves? I find that shelves are easier to access from the library tab than categories.

I was not aware of shelves until your comment, and then I had to search and find this article: Introducing Shelves for information. Thanks for the tip, and I will check it out.
