I'm not sure why the move and rotate tool is in a different place than the scale tool. below are 3 different gizmos from different programs, rhino, blender and c4d. I think rhino's is the clearest when looking at it, it's easy to tell which handle does what and Blender's has a lot of versatility by allowing local, global, normal (a surprizingly useful one), view, and gimble.
this is my first post so let me know if the attachments do anything funny
