Improving the default command:
Allowing the user to select a different axis each time the
default command is used.
For example, selecting a point, moving it along the axis
of an edge, saving it as a default command, and then
being able to select any point, use the default
command, and being able to select any edge to move it
along, or even better, any axis.
It appears as though the axis is saved in the default
command so that any subsequent time you use the
default command, whatever the selection, it always
uses the same axis. This lessens the effectiveness of
the default command. I believe Mirai had this capability
which allowed for very fast modelling if you kept using a
specific command but on different axes each time.
