use both sticks to move the cursor when you're sticking pins or just moving. This will make the cursor move faster. Hold the RB when you're cutting so it slows down and cuts more precisely. If you don't hold RB while using the scalpel, then sometimes it'll skip over the dots and then you have to back up.
