My final question for you lovely people is:

I want to sync my (built-in) notes with Owncloud as well. I know this can't be done out of the box, but are there any Notes apps I can sync with Owncloud and import the stock Notes into?

I know of ownnotes but I've heard I can't import with that.

It's no biggy as I can happily export the notes then re-import them.
