1. Ability to Tag Legend Components
2. Ability to rotate Legend Components
3. Option for "Floor Plan View" for Floors, Ceilings, etc.
4. Ability to Override Graphics, apply Filters, etc to Legend Components
Work arounds for these issues are too many, and leave too much room for error. A legend should be representative of the items in your model. It should have as much functionality as your floor plans do because it is meant to be a visual guide of the items in said floor plan. MUST HAVE FULL FUNCTIONALITY!
