idea for improving blender

i have left mouse selection enabled, and when i wat to select some vertices that are near each one to another, the manipulator is always in the way, i allways accidentaly click the manipulator instad of the vertices, I know I can hide him wiht ctrl+space but it would be better to disable the manipulator somehow when I first hold SHIFT and then start slecting, or when left mouse slection enabled manipulator should switch to rmb button, later when I want to use the maniupulator I can first start moving with the manipulator and then hold shift for more precision
