Hey, I'm the creator of Ummm. Not really on the roadmap anytime soon, but it's also still early for the product! Right now it's more about getting a grasp of what people want out of it, squashing some bugs and improving the UX further — before moving development further into a specific direction.
Have you consulted with any researchers on this project? I would suggest it would be a good idea to ask your target audience what kind of pain points you can solve for them, and I think your product would benefit greatly. As someone who would be your stated target audience, I can’t see anything here that would benefit me. As an example of my greatest pain point when conducting research would be organizing all of my research sources. The mind maps and cross references are a good start in this direction, but there are tools out there that do a much better job and are free. You’ll need to explain why this is better than all of those.

Looks like at least some people for sure want a way to store things locally and in current setup the only option they have is to ' want to be out of it'.
