The S3D supports have been really unreliable for me - my printer is dialed but it takes very little to cause the supports to accordion. Allowing a regular raft to be created ONLY where the supports are would solve this problem (I believe).
Also, with all this software can do, you still can't add an easy way to insert a pause commend? Go to "Layer view" and have a button that says "add pause" for a given layer. Please.
