Agreed, however I would like to be a bit more specific in how they should be altered, at least for my typical use cases.
I use rafts ONLY as a way to help support structure stick to the bed. In the same way that we can set the number of dense support structure layers under and above the part itself, I think the sense support layers between the bed and the support should be an separate option.
If a user still wants to have a raft under the part and the support, an option to put it only under the regions that contact the part would save considerable time and material. I understand how it is usually nice to have one big raft that pops off the bed easily, but sometimes this is outweighed by the massive time and material cost.
