Thank you for echoing my sentiments EXACTLY, Stop8. (Insert Thumbs Up here.)
I agree with everything you said.
The new System Tray icon IS very small ... TOO small to be supposedly conveying a useful, visible active scanning indication in that morphing manner.
It IS very hard to see.
It sucks.
It bites.
It is inefficient as one has to stare at it for virtually 10 seconds before one can somewhat half-bakedly determine with only 90% certainty that it IS active.
As it stands now, it's really just a System Tray Space Waster / Space Occupier.
Unfortunately, as some of the other members allude to, it is probably strongly heading in the direction of one of those things that is gonna stay as is, no matter what.
It's like way back when I tried at least twice to make a case for bringing back the Virus Definitions Download in Progress Indicator. Much to my disappointment, it just didn't make the cut of things to incorporate.
