Python Scripting ideas

For our final programming assignment, we have to create some python scripts for daily use in Maya. 

Some of my ideas would be:

-Display face normals

-Merge vertices

-erase history

-Mirror geometry

-cut faces

-soften normals

-fill hole

-add divisions

-add planar map

-smooth mesh

-export

-check local axis of skeleton

I think the 3 simple ones I'll do will be:

-display face normals

-check local axis of skeleton

-smooth mesh

(for a possible 4th) -add divisions

for the complex script: Mirror geometry
