Oh hush. What's the Most Important Killer Embarssing-Not-To-Have feature to one person isn't a priority for someone else. If you want it, add it. Mastodon is open source.
That's not my job, and that dismissive, terrible attitude is exactly why open source has such a bad reputation. When the people you're trying to recruit to use your service are saying there's a problem, saying, "Then you go do something about it!" is not going to endear you to users.
I don't feel the need to endear myself to users. It's not my job, either, nor is it anyone else's but yours. If you want something, you need to make it happen. What arrogance of yours to think that someone else should volunteer their time to accomodate for your whims!
If Mastodon doesn't suit your needs, then fix it or don't use it. Either way that doesn't make it "embarassing" or otherwise bad. It works great for millions of users.
And this is why commercial social networks tend to be so much more user friendly. They actually put effort into acquiring me as a user, because they can then monetize my eyeballs.
