I have no trouble dragging-and-dropping an image into the "Attach Files" pop-up browser, but several of our users are now asking if they can simply drag-and-drop an image attachment directly into the compose/reply window?
Trying this (at least in Safari) feels like it's about to work – the cursor positions with the image ready to drop– and then ... nothing happens. I'm assuming this is current-feature-set-expected behavior since the same thing happens right here. BUT... I figured I'd ask just in case I'm missing something?
