EDIT. AN IMPROVED VERSION BY CAMBO IS AVAILABLE DOWN THE PAGE. VISUAL CLUES, BETTER GESTURE DETECTION AND MORE!
Blender Mouse Gesture system has been around for years I think, but its funcionality is very limited. I manage to create new gestures in Python that override the blender original ones. I did this as an experiment and it amazed me that worked, specially since I´m a terrible coder 
If you like gestures or you like to use your mouse, give it a try. Testing is also needed by I managed to do a full session modeling without troubles. It´s kinda a strange hack using new features of bphyton so no guarantees.
It´s very usefull if you model extruding a lot… you know… extrude, scale, grab extrude rotate extrude and so on

[b]To use: Open the script in a text window, or just copy and paste into blender. Then activate it in the View -> Space Handlers Scripts menu in the 3D View.

# New Mouse Gestures v0.1 for Blender

# Feel free to improve, modify or just ignore this awfull code. I SUCK at math :D
#
# To use load the script in a Text Window and then activate it
# in the View -> Space Handlers Scripts menu in the 3D View.
# For simple customization you just search for EKEY, RKEY, SKEY or whatever key
# you want to change and replace for the new one (change only mode specific keys if
# you dont know python enough, ie: do not change scale(S) for separate(P) since it
# won´t work in object mode). Also don´t delete the fist line, it will not work without it.
#
# Note if you want to customize that some keys will not work (SPACEBAR, I, TAB and some others)
#
#
# Drag Up = Extrude (E) or Move To Layer (M)
# Drag Down = Rotate (R)
# Drag Left = Scale (S)
# Drag Right = Grab (G)
# Drag Up Left = Undo (U) or (CTRL Z)
# Drag Up Right = Redo (U) or (CTRL Y)
# Drag Down Left = Select All (A)
# Drag Down Right = Delete (X)
