I actually really like Mastodon as a fedi software and I don't feel like there's any *major* features that are missing from the day-to-day user experience. It's fairly simple and gets the job done, which I like. My only gripes with it are more like minor annoyances (like the poll answers limit) which are addressed by glitch-soc.
(still fingers crossed that tech.lgbt will swap to glitch at some point 🥺 🤞 )
