This is very close to ideal for me. I've been moving away from Google Keep (and google in general recently, using Fastmail, microg fork of LineageOS on Fairphone 2, orgzly, vim org-mode Nextcloud etc etc) and the one thing that I missed was easily been able to dump photos and images into notes.

I've had a play with this briefly and I will be using it full time. As soon as it offers nextcloud sync it really ticks all of my boxes. The terminal client is a really nice touch.
