Yeah the syncing issue has been hitting me more. Not as bad as Slack though, but still enough that where I've answered something on my desktop it'll still ring my phone. It's better than Slack because this is at least <5 minutes apart (Slack will message my phone >10 minutes after I responded on desktop). I'll admit that I'm willing to give Signal more leeway than Slack because they're small. But these things hinder growth.
But the features I've seen since growth are: 1) group call (which happened during early growth), 2) screen share on desktop, 3) color hinting in chats removed (which now results me in messaging several people I didn't intend to because I've been trained for years to rely on colors for hinting and it takes longer to untrain users. Thank god delete exists...) 4) mobile coin.
I'm still waiting on 1) usernames 2) channels 3) easy access to community based stickers (or just an official repository!). Things that I don't care about but the community does: 1) backup of messages 2) transferring messages between phones. Honestly after these two things a lot of other stuff is "cool." But these make it more usable. A 20 minute interaction with Signal users outside the community forums will illustrate how important these things are to people (the community forums have a real group think that's a big disconnect from what most users want). I'm all for more UX devs and making the app prettier, but it's no longer "early 2021" and we still don't have them (and have been waiting for years). It feels like there's a larger disconnect between devs and us users than there was in the past. People wouldn't throw a fit about MOB if the rest of the platform was moving along steadily and would probably be treated as "cool, but I'm not going to use it and have reservations." I'd welcome cool stuff like that, or noise canceling (featured in this update), or any other stuff if the rest of the platform was moving along.
I'm losing faith in Signal. I fought so hard to get my friends on board (years!) and now that we have critical mass it feels things have slowed instead of accelerated. It isn't just us "hackers" and privacy conscious people anymore. To the devs reading this: I love you and appreciate the work you do, but help us out here. We don't understand why these weird decisions are being made and they feel like step backwards instead of forward.
