I'm working on control pages for my A/V setup to replace my aging Harmony remote. One of the Harmony features I'd like to emulate is a button for "Current Activity" -- I want to be able to flip among various device-details control pages and jump directly back to the main page for whatever A/V activity is running without having to back-back-back-back to reach it.
It's easy enough to set a variable when launching an activity, but I can't figure out how to make a single button launch different control pages depending on a variable state. Is this something I'd need to cobble together an IWS plugin for, or am I going about it the wrong way entirely?
