As it was tricky to squeeze everything onto a small screen I did sacrifice the note button to leave a bit more space for the image. But we'll try to come up with some other solution, perhaps we can use icons for the "Save" and "Add a Note" buttons on mobile and fit them in alongside each other at the bottom of the screen.
I've added this to our list of things to fix (here) and will report back when it's done. Thanks!
