- real debugger (this is doable currently, maybe two person-weeks of work on the VM, and a similar amount of work on the IDE to support)
- Taking the CV class (and maybe the most recent Responder refactoring) as a basis, and build a robust general signals solution for connecting UI, synths, buses, data. Connecting UI/controls to synths easily and elegantly is one of the hardest and most annoying things for new users I think, and doesn't really get much more elegant if you know what you're doing.
- Proper npm-style package manager. Ach. (Been working on this for ages)
