I am in favor of separating the feed over ride from the rapids for sure. That and the lack of jog while paused drives me nuts.

No feed _can_ be faster then rapid - rapids moves at the maximum allowable speed. I should also explain max velocity better. Max velocity controls the absolute maximum velocity limit of the axis. it is set by INI settings. Turning max velocity down limits rapids first but if you turn it down enough it limits feed rates all the way down to zero. What it is doing is limiting the absolute axis speed, regardless of Gcode command. Having a separate rapid override allows one to set feed to 100% and the rapid to 10% while proving a program. This allows you to sneak up to the part while still cutting at the proper rate. You can do this with max velocity but if you really want to creep in rapid, you must turn the max velocity back up to feed at a proper rate. As I said IMHO this behaviour is not terrible, but separate is better.
