More options during Transforms (Move, Rotate, Scale)

Many times, I am using eg. Scaling, I forgot to switch Transformation Orientation or Transform Pivot Point appropriate in the given case. In one case I need 3D Cursor, in another eg. Median Point. And there is no visual feedback, except top bar icons or viewport axis lines.

I would like to have option like eg. Vertex/Edge Slide modal operator, where you can use shortcuts such as (E)ven or (C)lamp. During this new Transform you could switch these Orientations or Pivots with specific shortcuts. Just like switching between x,y,z axis now. And than you have live preview feedback of your action. Would be handy for all transforms such as Scale, Rotate and Move.

I would appreciate any comments. Thanks a lot.
