When you print a part with multiple brims in different locations, the gcode does one outline on each brim and moves back and forth between them all until all the brim outlines are done. It seems like on multiple brims, you could just finish one (including the actual 1st layer of the part inside the brim) and then move on to another brim for the remaining portions of the part. It would be quicker and more precise than bouncing al around doing one outline at a time.
Hopefully this makes sense, I am rushed to write this and I don't think anybody would object to this change.
