I often need to move ICs when prototyping and whilst I can delete the IC then import again to give an unconnected IC, it lwaves all the tracks behind. Could we either have an automatic rip-it-up feature where all floating tracks and vias are removed back to the nearest valid connection they tee'ed onto, or at least the ability to select lots of tracks by hand using Shift-Left Mouse click so I don't need to press the Del key 100s of times.
