Interact with objects on different artboards
In prototyping I need to be able to have an interaction transition not just between artboards but to a specific object on a different artboard. For instance prototyping a light box pop up, it needs to be able to be closed and take me back to the button I clicked to open it. This is a really common style of interaction. There are workarounds but they reduce the "realness" of the prototype when presenting.

Apologies for not getting back to you sooner on this. One thing that you might want to try for the lightbox scenario is to create an overlay, which would then lock the artboard behind you. When it dismisses, it returns to the original state. Also, we released a toggle state shortcut that will automatically create linkages between two states back and forth, so it should help with your second question. Let us know if this doesn't answer your question.
