Resource integration; Allow project files, or even entire projects, to be from IPFS (this will need MFS integration or IPNS or both in order to mutate data).
Publish on IPFS (add/pin); Publish your project - say a website - directly on the IPFS network. Might need integration with pinning services.
IPFS/IPNS linkify; Very situation dependent but ipfs:// and ipns:// links should be clickable links.
There's many more possible ideas, just throwing these 3 out here as starting points.
Developer integration in Visual Studio Code. Probably needs to be a plugin.
