If it really bothers you then adjust the clutch cable. Where is the clutch starting to grab? If its near the end of the lever travel then you need to tighten up the cable a little. It should move a little when going into first but it shouldn't roll if you let off the brake on level ground, if it does your clutch isn't fully disengaging and probably just needs to be adjusted. And shifting without pulling the clutch isn't bad as long as you let off the throttle when doing so.
