I would like to request a feature of move tool that would move the content of all selected frames in animation mode (this also applied to on-canvas selection of all selected frames). This feature would solve a problem of repositioning a desired part of animation.

Reproducible: Always

Steps to Reproduce:
How I would like it to work:

1. Create an animation (several frames length)
2. Select half of the frames
3. Move your selection around the canvas

Actual Results:  
Currently only one frame is being moved

Expected Results:  
I think it would be a good if all selected frames could move - which would result in repositioning the half of the animation (in this particular example)
