Savings plastic and materials.

[rajaakahel]

Hi, I would like to see a feature that saves plastic when printing multi materials/colors with one single nozzle like Diamond hotend. Instead of extruding plastic outside the main print to clean the nozzle, it can be used in the same print as infill for example. Other options than infill would be appreciated.

Another feature is to save PVA material, like the ability to use PVA only near the part (when supports are connected to the part) not the whole support with PVA.
Thanks.
