I often modify part of the path or single point with basic tools. For examples, it's quite convenient to select one point and rotate it, if I want to change the angle of it's handles, or scale it, if I want both rotate and scale. Unfortunately, AI hides handles when I drag my selection with a chosen tool. It makes sense in general, but I would like to have an option not to hide it, so I could see where my handles are all the time of transformation.
