Being able to name grouped widgets and add interactions to them is absolutely awesome! I love not having to create a bunch of dynamic panels just to make a collection of things work as one. That always felt so tedious and clumsy. The fatal flaw, however, is that there is no “Add to This Group” option. I can create nested groups, which is excellent. However, I want to be able to simply add additional widgets to the same group. There is no way to do that right now without ungrouping the original widgets first, and this causes you tolose all of the interactions that you created on the group. Essentially, there is no way to modify a group’s contents without destroying it completely (including all its attached properties). I want to be able to introduce additional pieces to my group while still maintaining the attached properties and interactions.
