I can't deny the benefits. But in my mind, this is not what ell should take care of. It doesn't intend to store anything whether in a text file or any other format. It should however provide the posibilities for users to store them in any way they like.
Fair enough. I seem to recall a project for keeping infinite bash history that did leverage SQLite - interfacing with such a project might be more interesting.
I was more thinking from gp comment that the project might store context or history in its own files - and then SQLite might be a good fit.
