The current automation actions effectively make changes in the ‘backend’ (update things, link things, create things etc.) which may or may not be immediately apparent on the UI of any given user (it depends on what they are viewing).
I think it will be some significant work to alter that paradigm, in order to allow that an action affects the navigation (for a specific user) on the UI.
Indeed, Coda have some amazing stuff, including some very sophisticated formula-driven functionality. Hats off to them.
Have no idea if/when Fibery will ever catch up in that area.
