I bet all of you know that “oh no, not again” feeling when you find yourself accidentally dragging some elements, because those have the tendency not to be locked although they better would. I feel such moments not only annoying, but especially embarrasing when I am in a collaborative session and I know that all my collaborators will soon seen their background was moved by some moron… ouch.

So PLEASE, implement the same thing you know from a lot of desktop applications (Windows Explorer, MS Office applications just to name a few), which is that you can “escape” from such an unwanted action (i.e., a started, but not yet completed drag & drop action) by simply hitting the ESC key before releasing your mouse button.

Should be very easy to implement, and again, this is undoubtedly a standard feature in complex applications that use drag & drop, especially when the execution of the unwanted action comes at some “cost” (here: transfer of the action from the front-end client to the back-end and from there to all other front-ends participating in the current session as well as the much more important UX aspect of the user that initiated the drag & drop accidently being worried/ embarrased/ panicking a little when she realizes the risk of an imminent face-palm as well as the unneeded irrritation of the other collaborators).

TIA
