Also the map scale could save a little space by showing the scale as the 32 pixel height of the screen and adding small serifs to the vertical line that separates the map from the text fields.

Good idea. I actually thought of that one last week and forgot to mention it.

Don't even need the serifs. Just document in the readme that the scale represents the height of the screen and be done with it.

And just an unrelated comment about the route screen...

In the "to do list", there's mention of trying to figure out how to rotate the whole map screen instead of just rotating the arrow. But it also mentions the difficulty that causes because of the short/wide screen aspect ratio.

If map rotation ever makes it into the software, I'd want it to be optional, because I actually prefer to have the map screen stay oriented NSEW and have the arrow rotate. But for those who want the map to rotate, you could optionally make the "target direction" be sideways instead of up, and have the arrow be off-center by 30 percent, so that you can see more of what's in front of you.
