A feature that would be simply excellent is if you could make the schematic shapes dynamic. Example:
A Industrial Display do usually have some built-in inputs and outputs plus one or more slot in ports. Then different slot in cards with their ins and outs.
When adding a plain product only the default I/Os is visible in the shape. If slot-in cards are added as accessories to the main product, also the I/Os for the slot-ins will be visible in the shape.
There is also a lot of audio and video products that uses slot-ins. Not to forget several Crestron CPUs.
When added to a project the shape acts as one and you will be able to move all Ins and Outs up and down to fit the wiring in your drawing.
If you could make this happen - I'll buy you guys a beer at ISE
