Please add the ability to select multiple elements, and move them all in along the timeline.
Yes I totally agree. Plus it would be nice if there was a way to group the object too.
It would be even nicer if the pasted items retained their original animation settings. Right now all items revert to "Draw" animation, even if set to "Move".
As of 2.3.7, multiple items still can not be dragged to a new position in the timeline (though they can on the canvas, as noted above).
