I guess the this user meant "how many level of depth". is there a limit to how tiny those bubble can get or not.

Haha I was looking for this one!

Curious about the issues you faced on mobile!

At Slite I was part of the mobile team, and the editor is using Slate. So to make it work in React Native we had to go for a WebView (similar to what Notion uses), with all the downside it can bring..

I tickled with the possibilty to do a native adapter of Slate, but the fact that it's based on a content editable, makes it complicated to adapt in React Native..

I have the feeling that block approach might fit better a more native integration on mobile. It seems similar to what Craft does, isn't it ?

Mostly Android input being a hellscape, and wrangling React inside ContentEditable posing weird synchronization challenges with input method editors.
