Improve email drag-and-drop

[srmalloy]

For those of us who may not be as deft with a mouse as we were in our youth, can the requirement for position for drag-and-drop of an object (enhancement, salvage, merit, inspiration, recipe, etc.) into an email message be broadened so you can drop the object anywhere on the email window, instead of needing to get it within the little attachment subwindow?

Sometimes I play on my laptop and hitting that little square while using the touchpad can take a few tries.
