Hi, wanted to see the points in order to rescale stuff (e.g. making the blocky end thing shorter etc.) This was just an example, the usual usecase would be direct editing of stuff with precise dimensions.
Thanks for the animation, I still don't completely get what's going on :)
But I also don't want to waste your time as this is hypothetical at this point. Michael already gave me the advise I needed.

Edit: Ah, now I got what you did, you selected everything and then clicked on separate, so all faces are separate objects now. On first glimpse this occured a little bit radical, but with box-selection (selecting all the overlapping points) one can indeed change the geometry of the shape that way. And then rejoin stuff once done. Thanks, this could come handy in some cases!
