I would like to see Autodesk develop a "flavor" of AutoCAD/ACA that caters to the Interior Design industry. Perhaps there can be a plug-in for ACA.
We in the I.D. industry rarely draw doors, walls, stairs, foundations, etc. We deal more with finishes, patterns, specs, notes, schedules, details, and elevations. Simple intuitive tools for modeling custom furniture with common materials would be fantastic. Also, the ability to EASILY switch between various design concepts would be extremely beneficial.
