setting temp by layer is nice but different temperatures, even when printing with same head are very useful
- general temp
- overhang temp
- small layer temp
- support temp
and whats most important imo
- support interface layer
- object "touching the support"
I'm not sure how these temp options disappeared from slicers over the years, initially all slicers had them (adrian's repraphost, enrique's skeinforge..) at least the basic interface layer's difference .. now I can't find them nowhere

and I would really like to get them back
