I wanted to try a demo, but they require you to sign up for an account and configure it with email access, etc. Too painful for a demo.

That’s the kind of thing Apple’s software explicitly tries to support. There’s a reason this stuff works better with native apps.

No, and probably won't be. Each tool is intentionally standalone. You can link to things manually but there's no cross-tool wiring. I'd rather keep the codebase simple and each tool easy to understand on its own.
