I am creating posts with many images. Every time I use "Insert Media" to place an image I have to use a dropdown to choose the size (Thumbnail, Medium, Large, etc). If size were select-able in the same way that alignment is select-able (no dropdown), then the size of the image could be changed in 1 click instead of 2 clicks.
The same goes for the hovering alignment & edit tools above an image (for an image that is already inserted into a post). Why not add the size directly in the toolbar instead of forcing the use of the edit button then the dropdown list of sizes?
Of course keyboard shortcuts for size would be great too!
On long tedious posts with many images, this could really speed-up work flow.
