Hi, @scottjl. Yes, I'd seen your thread and saw that you were new.
Welcome, again, to the forum. If you continue to participate you'll learn that this is one of the friendliest and most helpful forums on the net. You'll be amazed by the generosity and positive attitudes here.
Like @kevinb, I assumed that you might have something to upload; that's why I included the boilerplate that I often share when I spot a new forum user.
Thanks for doing that and I understand the challenge of sharing a custom configuration.
In rereading your approach (my memory is bad), I see that it has some overlap with the techniques that I use; but there are several key differences. As you probably know, Keyboard Maestro often provides many ways to skin the cat. Each technique often has advantages, thus you'll see many cases in this forum where overlapping techniques are shared (and appreciated).
Above, I tried to explain my approach (because my palettes also include information irrelevant to others); but then I decided to follow-up and share a mock up. I did this because I could see that my description was deficient and based on experience here (and my own learning style) examples are often used and well-received.
As @kevinb stated, it's certainly your call; but something to consider now and in the future.
Have a great day, @scottjl and all others!
