In the future we'll do two things (1) a built-in marketplace, and (2) a pro account with powerful collaboration.
The marketplace is a space where Vectr users will be able to create/share/sell design assets to one another. The pro account will include things like built-in version control, clickable mockups, prototyping tools, etc.
Vectr CEO here. We've been building Vectr for a few years, and just came out of beta today.
Hope you like Vectr! Happy to answer any questions you may have ;)
