I use it all the time for quick notes at work, with its very simple interface, and the tabs feature was a game changer. Especially useful for phone calls in my case, although my typing speed far exceeds my writing speed so maybe I'm the exception because of that.

The only Google thing holding me back from full degoogling is YouTube, but with how garbage the platform is becoming, especially with the algorithm just going berserk and it probably not being long until I start being affected by the adblock-block, I think moving away from it is only going to be easier than ever before.
