Manipulator >> Average Normals

Hi IStonia,

When/if you have time, would it be possible to have the ability to set the manipulator to "Position" and/or "Orientation" of manipulator the "avarage normals".?

For example.

Create a cylinder with no end caps(tube), rotate(random) around an axis, freeze orientation.

When selecting all the polgons on that cylinder, there is no current orientation(for the manipulator) to use average normals(which would be (position)center of cylinder (orientation) Y_up along cylinder axis.
------------------------------------
Not having this possible orientation also shows(as example) in an issue with "Extrude to average normals", which does not extrude in correct(average normal) direction.
There is also an issue with "Extrude to average normals" when "By individual polgons" is used, as rather than attemping to extrude in expected direction, the individual extrusions are made to individual polygon normal directions.
