I don’t know what anyone else intends to do, but if I can fix the issues I’m currently looking at – and no one else has stepped up in the interim – I’ll at least take a look at the 1.0 stuff. (I use mlmym and would like it to keep working…)

the thumbnails now are even more clearly 4-pixel potatoes

pictrs’s thumbnail parameter uses dumb raw pixel sampling – which leaves something to be desired… It has other sampling options implemented (with resize, according to the docs), but they don’t seem to accessible on my instance. You can remove thumbnail=96 if you want to get the image without that thumbnail sampling, at least.

make everything zoom 150%

I do this with my browser’s UI (ctrl-plus keyboard shortcut in FF-based browsers works for me).

e.g. right side bar

[...document.querySelectorAll(".side")].forEach(sidebar => sidebar.remove())

You could also just adblock the element with class side.

someone forks and maintains it.

MrKaplan already forked it and is keeping it on life support for lemmy.world. I’ve been trying to make enough sense of it to fix several issues that have been bugging me for a while, and will contribute my fixes there if I can figure them out.

I’ve only got a few hours each weekend where I have good concentration + enough free time to work on it, and don’t know the relevant languages (Go, Rust, TypeScript), so my progress is pretty slow… but I’m still poking at it.

Voting

You could support this by making vote buttons submit a form if JS isn’t enabled. (That’s what mlmym does.)

Can’t manually switch between dark and light mode

Hmm… There are some pretty nifty things you can do with a hidden checkbox, label, and some clever CSS (e.g. html:has(#element:checked) + CSS variables – though FYI :has is baseline 2023.)

Making it persistent would require some more effort – e.g. form + cookies + server side style sheet selection, most likely. mlmym lets users change their theme w/o JS by submiting a form on the setting page. I’d have to think a bit if there’s a good way to make it persistent across multiple requests for logged out users with a CDN caching things in between though…

only automatically based on browser settings

Doesn’t actually work for me in a FF138-based browser w/ JS blocked via NoScript – I always get light mode despite having a dark mode preference set. (Where do you have your prefers-color-scheme media query?)

Also, FYI I had to manually override font restriction – otherwise all your buttons end up as tofu characters. (I think NoScript is being kind of unreasonably strict there by blocking first party fonts.) That’s a papercut kind of issue, but figured I’d point it out in case it might save you some debugging time if you get confused NoScript users in the future.
