I think it would be nice to be able to open the settings of multiple transformers at the same time. Currently this is limited to only be able to open the settings of one transformer at a time.
I know there is a workaround to this by turning the summary annotation on so that you can view the settings, but it would be nice to be able to open two separate transformers and view/edit them.
It can be interesting.
I agree that this would be very useful. At times I need to refer back to the output of a previous transformer however when editing a transformer I can only see the output of the current transformer in the Visual Preview. It would be awesome to be able to interact with other transformers (even if only in a read only capacity) and also with the visual preview enough so that you can scroll along to check values etc.
Good call on this one @Chris Warren
