Extrude Edges will be available from 3.8.6
This tool allows you to extrude selected edges to create polygons by manipulating the gizmos i.e. Translation, Rotation and Scale.
1 and 2 processes can be inverted. Namely it's okay to enter "Extrude Edge" after selecting edges.
With "Flip Polygons" clicked on the property panel the polygons created by extruding edges can be flipped.
