Hi @SandervG
Yes, a different color, such as what it does in the layer view.
Or, probably a bigger hassle for the programmers, a button that says "Show Support Material"
You are thinking much as I am, so that the view displayed is more representative of what the Ultimaker will produce. As you pointed out, perhaps what 0.2 mm layers would look like versus 0.04
Anything that informs the user of potential issues would be good. And perhaps said suggestions can be disabled in the advanced settings for more experienced users who do not want them/need them.
In my mind, I am still very much a newbie but learning more as I read the forums everyday. Not everyone has the time to follow the forums, so if Cura is tweaked to embrace the novice users more, that helps create a better experience printing
