Give it time for the Diamondees to respond.
Essentially, I've heard that Diamond was a bit of a beast for custom settings, but one would expect that for lots of set up options. Emerald covers most needs concisely, so those who prefer set it and keep it with their desired color, flicker and FOC for a while will want Emerald. But those who want gestures, changing flickers or specific FOC patterns will endure the programming hurdle happily. I've also heard the update with an express mode sounds like it can make Diamond programming more streamlined and get someone into an introduction of capabilities.
The above is just what I've gathered. I am afraid I have not scraped enough change from the car seats to reach Emerald or Diamond.
The more I look up the diamond the more I will make it work financially hahah, especially to take it to the last Jedi with me.. now to figure out with hilt. The lack of repsonses has made me do alot of research today and it seems well worth it.
