I have been an AUGI (Autodesk User Group International) member since 2004 and have submitted quite a few wishes for AutoCAD and Civil 3D. I also participate on their forums every so often. If you aren’t an AUGI member, it is beneficial to join.
According to their website, one of their directives “is to deliver the voice of the user community to Autodesk, thus assisting Autodesk in product development and giving users a say in the process.”
The reason I mention all of this is because AUGI is now collecting wishes for AutoCAD. If you want to see the software improved, you can have a voice through AUGI.
