From Utah to N.C., I have enjoyed using the terrain instrument.  (I'm using version 7.0.18)  I would like to suggest not making the red and yellow mountain tops flash.  I find the flashing very distracting.  I'm also concern about the possibility of vertigo caused by the flashing.
Also, thank you, Walter, for including the red/green airplane icon.  It helps me a lot when flying south.  However, I find it a little small making it hard to find sometimes.  I'd suggest a size of around 1.5 to 2.0 bigger.
Sorry for any typing misstakes.  I'm using my Android tablet to write this.
