[Bf-committers] access selection order via Python

[Jacob Merrill]

It would seem like the selection order system, as well as a "capture tech"
for recording a modeling session with time stamps, could be in the same
system.

These would essentially be a .blend that is a tutorial (like saving every
command to a log with time_stamps?)

as a option that is not on by default?

this way the "learner" could move the modeling session / etc forward and
backward in time, and read materials
the content creator could make and save in the log?

it would make blender education very fast.
