• The ability to block or blur-out posts and comments from a custom list of servers and not just specific users. The second some admins/mods give up on toning down the edgy “debaters” I don’t want to deal with any of that. Though I feel this would fit more as a Lemmy feature and not just a client one.
• As someone else suggested, keyword based filters, both for comment/post content but user names and link URLs.
• An OLED-friendly pitch black color theme.
• Swipe controls would be a really lovely one, like what they had in Apollo. Made it real easy to hide|downvote<->upvote|favorite instead of aiming for tiny touch buttons while reading with one hand.
• The ability to save a local copy of posts in case an instance goes down or if one’s internet is spotty, especially for servers offering useful knowledge.
• Cleanly separated history, subscriptions and bookmarks between accounts. This one annoyed me in RIF. I couldn’t keep a list of favorite subreddits per account.
• Muted video/GIF autoplaying while scrolling would be great, but I understand that one’s probably a pain to get working efficiently.

Yes, basically I just dream of seeing Apollo Redux for Lemmy/Kbin on Android and with strong content/server filtering. 😅 I’d absolutely spend 10-15$ on that.
