There's not a whole lot more they could improve if you ask me. Much the same as paper books aren't seeing improvements and upgrades these days.
One thing that would be great, but we'll never see, is some kind of "universal location syncing standard". So that your side-loaded non-Amazon book on your Kindle could sync your current reading location with Moon+ reader on your Android cellphone and with iBooks on your iPad. That will never happen because all these different companies want to make higher profits by keeping you locking into their walled garden. But I can dream...
I currently sync Moon+ from my Fire tablet to my Android phone using Moon's built-in WebDAV protocol communicating to my self-hosted Nextcloud server. That syncing works great, but the Kindle - my main reading device - is left out of the fellowship.
