Boost For Lemmy

I tried all the clients that are out there and no matter good they felt alien as I was accustomed to using Boost on Reddit. Now that the lemmy client has come, it's like I'm using reddit now. The only thing that bugs me is most communities didn't move from reddit and I'd have to continue using the official shitty app to engage with them.

Also I wanna know whether this one time payment would be all to access all the features or does the dev intend to go the sync route and offer something like ultra tier?
