would be very useful to be able to add text/images/annotations directly in CAD view and not only in in the plot editor. it is a basic feature in most CAD programs...you could also expand it to something similiar to the 'callout' feature in vectorworks which is amazing.
Most of this is already possible. You can add an annotation to any object, just write something in the Unit property. You can also add images, use the Image object from the library, under Built-in / Dimensioning.
