F3 scrolls thru... hmm labels at least, maybe pings too, not sure actually, but I just use it and its great.
Again something that BA did great, if I remember right pings leave a small icon on edge of screen toward the location where it happened, and clicking on it jumps you to that location. Small things that make life happier.
I have many times noticed labels or important pings minutes after they happened. Even if someone writes my name on chat I will not notice. Again something that was somehow much better in BA; noticing chat messages.
Would be cool if you make ping directly on someones unit, it gives the owner a special notification. Dozens of times it would have helped a lot if the other person would just notice the situation even with no text(your com is going to die if you dont move it right now, move that idle ultimatum now, use these idle cons to reclaim, stop firing that tremor on my advancing units...).
Or have labels text show as transparent text on side of the screen for 20 or so seconds, right click to delete, left click to go to the label.
