I will try reuseItems again. It's something I tried before briefly but thought it may have been causing some rendering glitches and removed it. Maybe because I didn't implement onResused or onPooled properly. Thanks!
Yes, but without QTextDocument as I had some problems with it. I had to implement my own undo/redo/copy/paste/etc.

Yes, I've experienced some (minor) glitches that I've yet to figure out how to fix. For example, the cursor seems to (sometimes) jump when creating new blocks. Sometimes delegates reappear with animation (while I turned them off when onPooled ran). I'm trying to figure out if I'm doing something incorrectly (highly probable) yet I don't get these issues without reuseItems.
Sure, I hope it works out well for you (:
Regarding no.3, what do you mean by QTextDocument? My block editor is implemented by each delegate being a TextArea (inh: TextEdit), and it's very fast.
One trick I've learned, is to use `reuseItems`[1][2] in ListView. It gives incredible performance boost. You'll need to adjust some things according to the onPooled and onReused signals, but it's a no-brainer for many use cases.
