Angle Unit to display Angles
Angles, both in version 3 and in version 4 of GeoGebra can be entered in degrees or radians.
However, in the menus of version 3.2 there are an option Angle Unit that determines whether angles are displayed in Degree (°) or Radians (rad).
There is not option Angle Unit in the GeoGebra 4 menus (and the online help seems to confirm that indeed this option do not active in version 4).
Having seen this,... it exist any way in version 4 --command, button ,...-- because the angle measures be shown in radians???
