Connect does. Think it's having issues with loading from catbox right now though. Not sure if that's a connect issue or catbox api issue because it's happened before.
You can save posts, at least in the web view of Lemmy but whether a particular app has it or not I don't know. In the web view it's the star icon to the right of the reply button.
I'm using Sync and when it was Sync for reddit I believe it was possible. Perhaps it's now a premium feature, idk. But I'm not paying for premium when the developer goes dark between updates. Not saying his development method is wrong, but it's just not for me.
I'm only aware of one app that can do this: Boost. But unfortunatly, it's proprietary.
Thunder currently has an open issue for this, the dev is quite open to working on it. They want to rewrite the post area of the app anyway, so that's when they will probably add swiping between posts.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !boostforlemmy@lemmy.world
