Moving notebooks and creating subnotebooks

New Joplin user. Posting here because I think this topic is more relevant than discourse.joplinapp.org/t/sub-notebook-creation-in-the-mobile-app/

Now with Joplin Server gaining traction, Joplin becomes an even more appealing option to choose from many self-hosted alternatives. But I do think that the missing subnotebook management in the mobile app is the only critical feature that I'm missing to be a totally happy Joplin user on a daily basis. Sure I can go with a flat structure of notebooks, but I don't like the idea of collecting a lot of them over time and wasting time structuring them as a tree once the mobile app will get this very desired feature. Hence I'm bumping this thread, that did not have new posts for one year.
