Notifications are a pain point:

giving people the ability to curate their notifications. Notifications are what’s driving them nuts. Not posts, not even the technology of Mastodon – it’s replies from assholes.

They need notifications grouped, they really do. Hell, I want that enough that I mostly look at replies from my phone, where I have an ap that groups them.

They need to be able to turn on something like Twitter’s old “quality replies” filter, which served as a junk filter, and a block against pointless below-ban-level negging.

And they need to be able to do it at scale, because if you have 100,000 followers, you can’t reasonably do it one at a time. It’s simply not possible.
