The title is really self-explanatory. I'd find it very helpful if it were possible to see the note text from a via point in the Android app. To me, that would serve as a reminder exactly why I made that note, so as an example it could be the closest point to some food store where I might consider to shop, if I happen to be passing there at a convenient time. For extra bells and whistles, a checkbox in the note editing dialog could serve as an indicator whether or not this is something I'd like to pop up on my screen as I approach the via point (the note MIGHT be just for my route planning purposes and irrelevant when I'm on the road).

Edit: I just noticed that this overlaps with a comment from Hobbes on my "Personal POI" request. See? This is definitely something we need! ;-)
