I'm loving the direction Cura is heading in.
Just a few things I would like.
If you have settings hidden in the feature tree then the ones shown should trump what's hidden. Eg. Speed, if you have only print and travel speed shown then infill, shells etc should be same as you set print speed.
I like to adjust top bottom layers but number of layers not by distance but I like to have the distance shown just so I can see how thick it will be. But if I change the amount of layers, the distance won't change, then I don't know which one it will actually use.
