Today I am editing G-Code, again.  We have a project with thousands of 1.5" holes is 1.5" hardwood.  What I am doing is programming this with a step cut, first at .75 and then at -0.0050.  The issue is that Microvellum has never figured out how to ramp from the first to second cut.  No we have to raise the tool and start over for the second cut, this is a huge time waste.  So I edit the code, it's actually pretty easy, to ramp from the first to second cut.  I have been doing this for years all the time hoping they would eventually get around to spending a little time bringing the machining area up to the same level as the rest of the program..
