I'm not proud of that answer but to be fair there are also more balanced views in this thread. It's also an old thread and some of what's in there is no longer relevant. For example someone recently created a prototype of the app that saves the notes to disk, and although we can't merge his work as it is, we plan to investigate and see whether it can be somehow integrated.

It's one of these features that, all things being equal, we'd rather have than not have, but it's obviously not trivial to add it when the app wasn't originally designed for it.
