I don‘t think we are using EN the same way. I normally use it for university and other projects.
Yes, I could use tags and I am using them. It would just be an extra feature which would make searching notes a bit faster (for the way I am using EN).
I don‘t know why you are so negative idea. I would like to know what would be so bad if there were deviders. (Why are you „defending“ the idea of tags)
I don‘t really get your example, I am sorry (none native speaker)
