The Scene-Machine (or some variant of your nifty Code @wackware) should be a standard SmartApp by now.
The concept of a lighting scene (or “mood” as some systems call it), such that a set of lights is turned on to INDIVIDUAL pre-set dimmer levels for a certain activity (movie, romance, wake-up), is ubiquitous in automated lighting systems.
Actually, it is the SINGLE automated function that lighting centric HA systems are based upon (e.g., Lutron, HUE, GE Z-Wave master remotes, etc.).
I made a variant of the scene-machine SmartApp and I use it extensively … and nearly every day.
Frankly, I’d like to license your baseline code and then put a version in the SmartApp marketplace, when such a thing is created; though, as I said, it should be a fundamental part of SmartThings anyway, perhaps with a custom section in the GUI.
