I think you can now see why the button needs to remain. It is a quick access to see all outstanding Terrain, Traffic, Obstruction, Airspace, Info alerts. You can't have a pop up for each of those, that would be insanely intrusive. I think touching the Button to see a list of active alerts would be great, but not getting rid of it altogether.
There are many times when I see 4-5 alerts come through fast and might need to circle back. I do like the option of Airspace or Traffic popping the QV, though I can't see it for every type of alerts.
Honestly, I believe the general feedback is that the alerting works pretty well, if anything we need to allow for reducing the amount of popup alerts.
I think this gives us a good amount of information to run with, thanks for the dialog on this.
