yes... I agree. I'm working on this too. The 2.0 UI will be all re-done in React, better mobile support, including transitions. So you will be able to deep link to other annotations by their ID.
Also, going to work on the ability to link them together with a search and auto-complete system so that you can just start typing tags, or the body of the note, and then they can be linked.
Also, while I can see tags being useful, I don't think it'll really be Zettelkasten-like until you can link from one annotation to another.
