I believe any two posts linking to the same URL are treated as a cross-post, and that is discovered at instance-level. There's nothing more to it than creating two posts in different communities with the same link.
ETA: But to answer your question directly, there's no support for doing that as a single action with Jerboa yet.
The setting is tied to your instance account, because the backend delivers the results with the specified sorting. If you change it via the browser, it should be reflected in Jerboa.
You mean a version later than 0.0.34alpha? Sorry, maybe I'm blind, I can't find it. Could you post the direct link?
You know, the main reason I didn't comment here earlier is that I find it basically impossible to narrow it down to 5. I'm always bumping against MAL's stupid "maximum 10 favorites per category" limit, where to make matters worse they decided that all real people are a single category.
That said: for voice actors, I distinguish between "breadth" (the range of different characters they can convincingly play) and "depth" (the acting skill of portraying a character realistically through a wide range of situations and emotions).
There are some seiyuu that excel at one of these dimensions. E.g. Atsumi Tanezaki has amazing breadth, from Mizore to Vivy to Anya to Futaba. Also Yumiri Hanamori.
Tomoyo Kurosawa has great depth, I don't think there is any other seiyuu who can play a teenage girl as realistically as her, with all the little vocal quirks.
But the greatest have both, breadth and depth. HanaKana, Aki Toyosaki, Nao Touyama, Maaya Sakamoto, Saori Hayami are in that category for me.
Thank you for coming to my TED talk.
Since account creation does not happen in the app, but requires visiting the instance's home page, where registration requirements, federation status and other peculiarities are plainly visible, I don't think this belongs in the app.
Protip: Unselecting all has the same effect.
I always liked reading along with the /r/anime rewatches, but never got around to really actively participate in them, partly due to lack of time and partly due to different timezones meaning that my comments would come pretty late to the discussion. Also a lot of commenters wrote these really long and elaborate texts, it was honestly almost intimidating.
That being said, this is a different, still much smaller community, and the bar for visibility is lower. I think it would work with an adapted format, like one parent post per rewatch with toplevel comments per episode. The default post sorting on Lemmy takes into account comment activity, so such posts wouldn't drop off the "front page" too quickly and not clutter the community either.
There was some discussion about doing airing show discussions in that format, but the counter argument was avoiding spoilers for people who are not caught up. But for rewatches, I don't see that being so much of an issue. In fact, keeping all spoilers for one show in a single post could even be an advantage.
