>>51973I am not a tech support but I am in charge of the site's interface basically.
"Arrow keys" are gone because they were a part of pagination component which was putting fucking global keyboard event listeners on every page it was in. The post page survived this because it had this logic specifically for the page, not some component used across an entire site.
If the custom hotkeys ever come back they will be opt-in in a separate settings page. Naturally it won't happen until there is a settings page.
Custom pagination isn't going to be a thing simply because it's extra cache keys on server per collection per pagination limit with no meaningful gain.
So points 1 and 3 are out, that leaves only the second one, which is a vaguely-worded feature request.
