Link looks a bit old, but thank you for the mention! :)

To add to your comment: I still have a part of my NLNet grant to deliver and it is exactly about integrating the Reddit-to-Lemmy onboarding process on any Lemmy mobile app - like alien.top does, but directly on the app.

I have some work doing that on a fork of Voyager, but if the Sync for Lemmy devs want to do it as well, I'd be glad to make the switch and collaborate.
