I love being able to paste an image from the clipboard in having clicked the insert image button, but I don't like needlessly clicking on things if I don't have to (mostly!)
Currently what happens is as below
Click this button:
This pops up:
Paste your clipboard that contains an image to get this dialog box:
Once you click confirm the image is uploaded and you get your markup.
I think it'd be great if we could just paste straight from the edit box, to be presented with the Add a Picture confirmation dialog box. I don't see the need for requiring the extra step of clicking the image button. Obviously it should be kept to allow for discoverability and because of the other upload methods.
onpaste
event and in case image is being pasted do the magic that is already in place.
