Yep, planning to keep rolling with it if there's interest. I mentioned this in previous responses, but the data is actually being saved. The unique Url generated when you first start will get you back to the settings for the model you're working on.

It's a stop-gap feature so that I didn't need to implement a login/authorization system in the MVP.

Could make it a viable side project by charging a fee to enable easy exporting, then be able to reinvest that money in improving the project.
