Im pretty satisfied with Lemmy, but one thing i wish you could do is browse instances. Like i wish there was a way i could almost emulate being on my programming.dev account and see all that instances communities while im logged into this account. Afaik theres no easy way to do that without visiting some aggregator website. It would be nice to do within Lemmy itself.
The ability to “subscribe” to a thread so you could be told when anyone adds to the thread. I don’t understand how people follow a thread without this. You would have to constantly be going back to it (over and over) to seeing if anything was added.
