Mouse over highlight

Is there a way to make the buttons highlight when I hover over them with a mouse? maybe 50% of their "On" colors?

Or maybe a new field where you can set the "hover color"?

A bit of css will do:

:host:hover {
  --alpha-fill: calc(0.1 + var(--alpha-fill-off)) 
:host:hover.on {
  --alpha-fill: calc(0.1 + var(--alpha-fill-on)) 

this is great! thank you!
