One quick note on Extrude with Set Path - it seems that there is a bug where it won't work right if you have a path with a kink in it with, if you have "Cap ends" also turned on.

I should be able to fix this for the next beta but for now make sure that Cap ends is turned off before you pick "Set path" if you have a path with a kink in it, then you can select the object and do Construct/Planar to put on caps after that.
