Yeah I'll definitely return. I find myself opening Boost by habit way too much lol. Lemmy and Jerboa are also a bit janky and I find the default pages and algorithm weird. That said it seems like as a result, or maybe just because of the low amount of content, posts stay active for longer, whereas most 1 day old posts on Reddit are basically dead.
I used to use the official app for a long time before switching to Boost, which is more usable and customisable, and also ad-free after paying a one-time fee. Just after I switched the official app made some unpopular changes so I didn't look back, but I recently checked it and it seems that there are a few new features introduced that I find useful, including being able to download videos easily which will be an essential feature if bots will stop working in the future. Playing videos are still janky though. If I'm forced to go back I'll definitely use revanced to strip the ads.
As I understand it the changes will be even more painful for the mods though, even if Reddit promised to not touch bots that help mods.
That said I've created a Lemmy account and downloaded Jerboa so I'll probably still use Lemmy occasionally just to see what's here.
I agree that the "world" concept is missing. Maybe make the white parts green and the green parts blue so it looks like a continent surronded by ocean on a planet? Not sure if that design will be as clean though.
