Undocumented features on the mini panel?

My big panel has lots of cool undocumented features, but I never bothered to check on the mini.

Are there any I should be aware of? Or is this something we can simply request?

What would be amazing is if the "user" button became a toggle button to enable alt- functions on the buttons.

If it's undocumented, how do you check?

On the big panel, some of it I found on forums. Some of it, by just pushing button combos and seeing what happens.

I suspect that evolved from the older panel that was upgraded over time via limited buttons. My assumption was that the newer mini panel was designed from scratch, and so would not have such features. But never hurts to ask.
