• Reports categories based on both the community, the instance of the community + the user to reduce report noise between mod actions and admin actions.

• Post tags, to label content within a community.

• Better language support, clearly indicating which ones are allowed when submitting something in the language dropdown, as well as basic language detection support.

• When the instance is using pictrs, add a section in the user's settings to see all the uploaded pictures in that account, with the ability to delete any of them.

• Better accessibility / a11y support for uploaded images with alt-text.

• Support for svg-based emojis

• For mods, the ability to make a pinned post made by one of the mods editable by other mods, which would be useful for FAQs, etc.

• The ability to subscribe/follow a specific user, not just communities.

• Passkeys support as a 2FA method.

• Some basic builtin automod action, such as blocking known keywords from spammers from being posted, not just showing as removed as when using the slur filter in the admin settings.

EDIT: Something I just thought of

• A URI protocol handler to refer to communities, users, post and comments in an instance-independant way (ie: lemmy://u/mp3@lemmy.ca, lemmy://c/asklemmy@lemmy.ml, lemmy://c/asklemmy@lemmy.ml/p/1234567) or another syntax that makes more sense. That way you could let the OS redirect the query to the software of your choice, and define your home instance there.

Now there are some issues to figure out before defining the URI handler, like how to refer to a post or comment that will redirect to the appropriate one on your home instance since post and comment currently have a unique ID on each instance, which makes them hard to directly address without doing some kind of conversion.
