[slice tool snap to grid?]

And Designer 2 is released and still no improvement on the export persona slices.

[Transform (resize / position / etc.) multiple slices at once]

After all the time the only valid workflow for me is to go through all Slice Layers with a screen Macro Recorder to set it to my target position and resolution.
It could be so easy and so helpful if the transform box would allow multi slice editing.
