tl;dr
Add transparency to the power/electricity warning icons when blinking is disabled.Why?
So, I recently disabled the "Enable Warning Icons Blinking" setting because I was getting concerned about monitor burn in. Primarily on the quick-bar since that blinking icon is always in the exact same location on the screen. (And the blinking itself really started to grade on my nerves).All was well... until I started designing factories without them being connected to power and noticed that I can't see any of the set recipes or filters on inserters because they non-blinking icons completely covered them up.
Transparency is just the easiest solution I could think of. No idea if it would actually look good but the main takeaway is just that the underlying alt-mode icons should be visible somehow.
