A few ideas for the selection tool (additional to #255):
[ ] Create the option that the selection tool selects the lines it touches and not completely encircles. (I think this was already mentioned somewhere but I could not find it.)
[ ] Add the options to change the color, line thickness, and layer of the selected parts.
[ ] Add a delete option. I know it is possible to cut and clear clipboard, but it would be smoother if there were a delete option directly.
