It’s definitely something we’ve seen demand for and would like to explore at some point. Since the Template Manager was first released in Cornerstone years ago, we’ve gotten feedback about having a centralized place to manage assets across many sites. I agree with you that Design Cloud is a good place for this type of thing to be implemented. The concept is something we’ve discussed a number of times. For it to work we’d have to A. Build a paid subscription service to manage assets through your Themeco account or B. Build a standalone plugin (not included with X/Pro) to serve assets from a WordPress installation.
Last we talked, option B seemed the most viable and appropriate. When the plugin is installed, the template manager would allow some form of tagging and cataloguing assets. It would also turn the site into a server that would allow remotely downloading assets from other installs. On the other sites ideally, you could just click an asset and use it directly from the remote server instead of having to first install it to the local template manager. There’s quite a bit of work involved to get there. Challenges to solve like caching assets, but making sure new versions are available.
It’s still just a few internal discussions and hasn’t materialized further so I can’t guarantee or promise anything like that is actually coming. It’s definitely something we’re keen to explore further. I imagine it’ll come up again during talks around this cycle when we’re retooling things in Design Cloud.
