I just happened to use Calc for the first time in a looong while yesterday. Pretty nice. Fast, conventional, no damn ribbon menus. Saved to office365 format for consumption by others and it was all flawless. It's always been functional, but what I saw yesterday felt pretty polished. Used whatever version is default with Ubuntu 24.04.

So, it's still being actively refined. I think you're maybe a bit too hard on LibreOffice and Apache.

Also, I'll mention something about Thunderbird. Because Snaps, I installed Thunderbird from the official site. I am amazed by this software. Thunderbird is legitimately a nice desktop email client. What amazing progress.

I wondered about updates for Thunderbird, thinking that since I'd done an out-of-band install, I wouldn't get updates. I was astonished to find it's been silently auto-updating itself with zero drama. Kudos.
