I'm not currently developing a Lemmy app, and I have no plans to, so this is not a market research post for myself. If anything, I'd like it to be a resource for existing developers to see which features the community most wants!
So, putting aside regular features (e.g. things that the Hard-R app already does), I'm specifically wondering about which less common features you all want?
Here's of one of mine:
I'd like to be able to limit my usage of an instance to a specific account. For example: I never want to post to LemmyNSFW from my main account. That's what my alt is for. So I want to be automatically switches to my preferred account per-instance when I interact with it (or at least give me the choice to switch on-the-fly when composing a post or comment).
You should be able to do that already. I use Liftoff and am able to interact with other instances just fine. Perhaps the instances you're trying to interact with have been defederated by your home server? I admit I don't exactly know how defederation works yet, but it's the only explanation I can think of as to why you're unable to interact with another instance.
I'm signed in to my lemmy.world account. When I try to upvote something from memes@lemmy.ml Liftoff says I have to sign in. I can view the post, I just can't upvote.
Sometimes I click something and I get a pop up that says "View from lemmy.world" or something like that. When I click on that, then I can upvote.
Anyway, I just switched to Connect for Lemmy and it doesn't have that issue. I'm signed into lemmy.world and don't have to care what instance a post is on.
