They need to fix the fact that you can't seem to directly place the slope on a ramp. You have to place it on some other element and then move it over to the ramp. The up arrow doesn't work right either.
Thanks for taking the time to submit your idea. Unfortunately, this idea did not get the support of the community over the last 6 months and as such we will not be pursuing it at this time. Please feel free to rework (titles and clear descriptions are really important) and resubmit this one down the road.
