Can you make the drag 'n' drop facility optional from preferences.

I usually select a lot of books etc with mouse only, but can no longer do that, if I try a select several items, it now tries dragging the first item.

Selecting several items is now a lot more cumbersome and time-consuming.

Edit:
Especially when not in one continusous block, you now have to select them all indvidually.

And mistakingly dropping a large amount of selected files, back into calibre is *really* annoying, especially when you've done it several times. (because I was trying to select another book)
