Group active application icons...
Is there a way to have active applications group at the left (or top) of the dock? I envision that icons would temporarily move on app. launch. Return to orig. position on Quit. It seems silly to have to traverse all of the icons for inactive apps. Using OSX 10.8.5. Question could also apply to Yosemite or El Capitain. I would be delighted to learn that Apple has actually introduced this behavior is one of those upgrades.
Thanks, Iverson
