I have an app similar to Zotero (Polar) and we don't sync with cloud services either.

It's a bit of an anti-feature. We can't really control the data store if you're monkeying around with it under the hood.

Polar already supports cloud sync so we encourage users to use that. Same with Zotero I imagine.

- The lack of developers and thus slow pace of improvement.

Do you mean the dev pace of Zotero is slow? I wonder if their legacy infra is slowing them down.
