Yes I can see they have added this in 6.4 SP and 6.5, but why would they
not offer the same asset picker button for dialog components like
fileupload? Instead the component is hardcoded to be tied with the page
thumbnail which seems like a wasted opportunity.Right now, if you opened
a component dialog with the left rail closed, or if you switch to full
screen mode, you cannot drag an asset into a fileupload dialog!
