I’m not suggesting this straight to the devs because come on, they got too much on their hands already.

Skin switcher

A drop-down menu allowing you to choose which style you want to use with Lemmy, like a built-in Stylus.

Reverse Slashdot voting system

You have one upvote (“like”), but plenty downvotes (“disagree”, “rude”, “unfunny”, “off-topic”, “incorrect”, “insightless”). So to downvote you’d click first on the downvote button, then again on your chosen reaction.

I’m suggesting this asymmetry because good content has often multiple qualities, so it’s sometimes hard to choose on which one to vote. Plus positive feedback should be as streamlined as possible, as it makes people feel good.

On the other hand, bad content has often an obvious flaw, and it’s more important for the commenter/poster to know why people dislike their content than why they like it. It would demand a bit more effort to downvote (two clicks instead of one), slightly discouraging people from mindlessly downvoting.

Custom sorting system

It would require a multi-dimensional voting system, as above. Let users sort their feeds by assigning a weight to each thing that could be used to sort it - recency (as in “new”), upvotes, each type of downvote, etc. So for example if you don’t care about coarse language you’d weight the “rude” downvotes as zero.

Bonus points if comm mods can set up a custom sorting system as the comm default. I could picture for example a discussion-based community ignoring “unfunny” downvotes for the sake of sorting, while a memes community would ignore if the content is off-topic.
