Hey guys,

Like most of you, I often print from different spools and it's getting to be a chore to keep all my slic3r profiles up to date for each color since each is a slightly different diameter and I use different slicing profiles (infill variability, support or not support, etc.)

It's usually pretty easy to tell right off the bat if the extrusion multiplier is slightly too much or too little. I was wondering if anyone has tried or thinks it's worth a try to allow the LCD knob to change the extrusion multiplier on the fly.

This could also help with the calibration process by allowing users to get a feel for what happens is the extrusion multiplier is played around with without having to go through a lot of extra PC work.
