It's a little weird entering my password into this other website, but I decided that a person who codes old.lemmy is probably trustworthy...(?) Anyway, that's one option for you.
Obviously it would be better if it were implemented locally at feddit.uk.
There's contrast and then there's a poke in the eye. Quite where that falls is subjective.
A feature I would like to see implemented is the ability to theme Lemmy. I was having a play with it on Calckey and you can really go for it on the amount of customisation.
