From my discussion with some beehaw admins and sublinks devs, a problem is they they feel like their code contributions will not even be accepted
They've never opened a single PR, whilst the github shows us merging tons of PRs from third parties, so that seems like negative speculation on their part.
For example showing voting totals.
The lemmy API already has open vote totals on everything (score, upvote, downvote), and I also made a PR adding a user preference setting for how to display scores for your user.
I believe there's an open issue for a plugin framework, but that would need to be fully worked out. If it's just simple preferences, there are tons of sample PRs to learn from.
I'm quite confused about some people's adverseness to learning Rust; it's been the voted the most favorite developer language for many years in a row now (for good reason), rust frameworks frequently top the fastest web server benchmarks now, and every real developer has to learn new languages and frameworks every few months to keep up to speed anyway. Just as an example, I was waiting for a messageease(an android keyboard) replacement, and nothing came close. I taught myself kotlin, and android programming, and made one, and I'm an incredibly slow learner and middling programmer.
