Hi,
Thanks for your feedback. Technically number "3" of the above is already possible, you can also share them with friends colleagues 😉

Regarding the other points, please know that we unfortunately can't comment on what's coming up... but know that we're not considering the modeling feature set "finished" by any means, and that we're actively working on extending the app further ;).
