Just be patient. The developer has been active in the boost community, and has stated that he expects release before the end of August. I'm using sync for now til it drops. Boost was my favorite way to surf Reddit and I don't think it's gonna change on lemmy
I was originally a sync user and switched to boost when the developer stopped releasing updates. Then sync made a comeback but boost was way better. Im using sync right now as well and im grateful for the option but i fully intend to move to boost
I haven't used sync, but content filtering was one of my favorite features on boost. I had filters like "opinion" to reduce the amount of opinion pieces on news subs.
I've been trying out Sync, and it's actually really good. It has a lot of content filtering, such as filtering instances, communities, users, domains, and also keyword filters. I just tested out the keyword filter to see if it worked, using the word "Trump", and it worked good. It removed all the posts about Trump.
