Edit: I forgot to mention In terms of the Apple Pencil body being too slick, I picked this up on Amazon https://www.amazon.com/gp/product/B01LY38UE5/ref=oh_aui_sear... It's not quite perfect but it's a lot better than vanilla and has a magnet that attached it to the iPad as well.

Nice, I've almost ordered one of those in the past. My idea was to actually remove the original body of the pencil and have a better one 3d printed for it. The cost/effort is probably completely not worth it, but it does look feasible per the teardown looking fairly straight forward.

I used Good Notes for a while, and it is a great app. However, I tossed the iOS 12 beta on a few weeks back and the updates to Apple Notes makes the pencil a lot better, you get stroke and color controls finally. Since it integrates so well with the desktop version of Notes, made it a no brainer for me.

I use Notability especially since the latest major update to add OCR to handwriting.

How well does it work? Could it preserve indentation during conversion?
