I see some issues, can I contribute? Pop this on a git and I’ll make a PR with what I see. Particularly, I see you prefetch the info for the userlist on page load, which is problematic. I think we can do better.
Thanks for building this! Love the concept. Really great idea that I was just thinking is sorely missing.
made a new github account today to post stuff like this
made the repo, here u go: https://github.com/lemmygod/lemmy-hovercards/tree/main
i am planning on improving a lot of things but i’m so busy with work. You’re welcome to make issues, PRs and stuff.
Awesome. I too am a bit busy, but I’ll take a look and start playing with it. We can def knock this outta the park, and then honestly we’re so close to that RES experience I’ve been missing lol
btw if you’re playing w it and have a few extra mins, im planning on adding buttons to send msg, block & perhaps even open in local instance.
something i just realized a couple of days ago is that lemmy ui uses bootstrap and i didn’t leverage this in the component i made, not that i know much bootstrap but some consistency and contrast would not suck. i’ll stop being so busy in a couple of weeks tho so meanwhile that’s that.
