A feature request of my own.

Is there any chance that a check can be added to highlight a road with a blank elevation? I've been running into two situations:
1) As I'm editing, I'm discovering blank elevations that I'm having to set as ground and then save, when then shows "ground" the next time I select those roads. This then results in my checking a lot of extra roads nearby that I'm not otherwise planning to edit to see if they've got the blank elevation as well. If the Validator highlighted empty elevations, then I'd be able to simply look around and know which ones need to be fixed.
2) I'll edit a road that already has a elevation of ground, but after I've made my edit(s) (none of which involve elevation), when I select the road again it will now be blank instead of "ground." This does not happen all the time - only for some roads. As a result, I'm wasting a lot of time editing a road and then having to select it again after saving to make sure the elevation is still right. If it is, then I move on and if not, then I change it back to ground and resave. If the Validator highlighted empty elevations, then I could eliminate the need to click on something I just finished editing simply to ensure that it's still set to "ground" and will only have to do it if it lights up after I save. (I sometimes have dead-end U-Turns that were green where the save at hard restricted didn't "stick" for some reason and reverted back to green after the save - since the highlighter lights up those roads, know I need to go back and do it again without having to waste time reselecting every dead-end I edit just to be sure the restriction is in place.)
So, any chance this check can be added? Maybe make it a selectable option so that those who don't care won't be pestered by them?
