More then the preview... more then manual supports... Multi-processes is the very most powerful differentiator for S3D... Yet you guys kinda make it a bit tedious to use.
Currently processes can be set to start and stop at a specific layer height... but S3D gives the user the layer number. The user then has to calculate what to put into the start and stop fields by multiplying the layer number by the layer height. S3D should do that for the user. The user should be able to set the start and stop without having to do the calc... so one approach is to change the start & stop to layer numbers or to provide not only the layer number at the bottom of the preview, but also the layer height in mm. or better yet do it interactively by letting the user set the preview layer then select a grab height button for start or stop.
The more users that see and use this incredible functionality, the more differentiated S3D will be from the freebie stuff that is out there.
