I find while roughing out a design I end up with many custom components each with several states. When I first start to create a component like this I will quickly create the expected number of states I need for that component. Then I start working on finishing off the first state. This often means changing some common element such as a background image slightly. The problem is there is no easy direct way to say make this change across all states. I end up having to remove from all states and then share back out to all states. It would be nice to have an option of making changes across all states or something similar.
Never mind just noticed that there is not a make the same in all states on a right click :-)
