Ideas for improving multi-image selection and context menu UX:
[ ] show context menu on right click if row isn't already selected? Finder does this and sets the item in some kind of semi-selected state. More applicable for acting on single images rather than groups. What if there's a current selection and user right-clicks on a row that's not part of it?
[ ] update focused image to the very last one in selected image list? It's a bit odd to increment the focus index after selecting a bunch of images and performing some action on them because it will increment to the 2nd selected image.
