It is actually very, very janky and behaves like someone tried to reimplement ~15 years old Office UI in JavaScript. Not in a good way.

I really, really want them to be successful, but I cannot pretend it's a pleasure to use at all.

When I tried it last, it was painfully slow. Have there been any improvements on the performance front lately?

Typing in a word processor should not have input lag in 2025. It wasn't just a little lag, but the type and watch it catch up kind of lag.

Could you be more specific?
