It would be very useful if you could select a bunch of objects of similar property sets and execute a command to copy specific properties from a single object.
For example:
I have 10 source arrows and 1 text box. I want the text in the source arrows to be the same text height as the text height in the text box. So i highlight all the source arrows and say i want to copy the text height from that one single text box.
This would be extremely useful to change multiple objects properties at once.
