Hi Raven, well I'm glad that you brought it up because an improved indentation/protrusion mechanism has kind of fallen off the radar a bit, it just hasn't been mentioned all that frequently, you can see in this "top 5 requests" thread that it's not really mentioned often:
http://moi3d.com/forum/index.php?webtag=MOI&msg=3628.1

There's been a lot more requests there for stuff like instances, groups, and deformation tools.

That's pretty much why it hasn't percolated up in the priority list more rapidly.

But I think it will be a good time to give it some attention soon here for v3 (for Extrude combining with a solid automatically and depth limiting for booleans with curves, editing an existing face by push-pull is more complex).

Hopefully the result should be more convenient than push/pull in batch situations, for example I'd like the "depth limiting" curve cut in the booleans to make a set of 2D curves and a solid like this:






That would be for doing a boolean difference with a solid and the curves. Right now you can do the boolean with a solid and curves but it will make a cut all the way through the object, the "depth limiting" mechanism would be the new ingredient. Then maybe for a protrusion rather than a cut you could use the boolean union command with a solid and curves selected.

That's the other thing - I try really hard to combine functions into a smaller number of commands when possible since that helps avoid UI bloat. Sometimes it can take a while before figuring out the details for how to combine things though too.
