I know I personally want to build a few app that run inside notedeck:

- A tab for the notebook app for tracking threads in an inbox/email-like fashion. Pin notes into your notebook for tracking

- a tab for the nostrverse: a 2d visualization of your social graph

I feel comfortable doing all this crazy stuff now because the local relay model is so efficient. Tightly integrated local relay makes all of these things actually doable. Just imagine if any installable app had access to this power 🤔
