I use regularly both libreoffice and collabora online and I can say the former is snappy compared to the second. It can take a longer time to open thought, mostly on Windows.
I briefly tried it : I don't see the point, there is no way to connect it to your online collabora instance or directly to Nextcloud or anything except your local files.
Just use LibreOffice at this point, at least it has native performances and is not an app bundled inside a browser.
People actually use this kind of software today ?
When I read OpenClaw description :
"The AI that actually does things.
Clears your inbox, sends emails, manages your calendar, checks you in for flights.
All from WhatsApp, Telegram, or any chat app you already use.".
It does not appeal to me at all. I wouldn't trust an IA agent near my mails, calendars, messages, flights or anything it could mess-up with. It sounds like a security nightmare waiting to happen.
Yes, it tooks me 2 years to see how much garbage strings conversion to String Names generates and how a fool I was calling something like Input.IsActionPressed("move_right") every frame (sadly it's the example given in the input documentation).
I'll add that C# have better performances than gdscript. It doesn't make a difference for most of the things you code in a game, but it comes in handy when needed.
