Good to know it will be a feature in the future.
I always wondered why most programs dont have that capability as zbrush.
Most like maya and xsi have a script editor that will record your actions as scripts. and will actually allow you to select snippets of that recorded script and run them to redo most tasks but don't seem to have the full flexibility a zbrush.
I usually use this method to redo some modeling that i would otherwise do multiple times or use a duplication method.
eg. i can create a circle and say duplicate it, loft between the duplicates etc. then all i need to do to recreate a similar model is to just draw a circle and run the script generated fron the first session to recreate the model... saves a bunch of time sometimes.

will be looking foward to this in toe future.

cheers!
