That's not a million miles from the way that I map right now, albeit 
without the benefits of an "app" as such:

I record a GPS trace (on a Garmin) with numbered waypoints in it. The 
symbols for the Garmin waypoints "mean" something, so the "boat ramp" 
symbol means "public right of way".  If it's a bridleway I'll add "BR" 
to the comment on the Garmin.  If more text is needed (e.g. the name of 
a shop I've created a waypoint for) I'll create an line in an email to 
myself, the start of which is the Garmin waypoint number and the rest of 
which is the comment.

When I get home I'll split the individual traces out programmatically, 
merge the comments from the email into the GPX file (likewise) and 
upload to OSM.

I'll then edit in OSM using the uploaded trace directly (using P2 - JOSM 
can't process waypoints in a way that's useful to me).  Usually the 
combination of new GPS trace, previous GPS traces, Bing imagery, OS 
OpenData StreetView imagery and my recollection is enough to figure out 
where the path should go, but none of those (unless there are really 
_lots_ of old GPS traces) are good enough on their own.

On an introductory level, I can definitely see the benefits of something 
that can suggest to people "here are the other attributes of $thing that 
you've just added", like iD does, and like Kort does/used to do (see 
http://wiki.openstreetmap.org/wiki/Kort_Game ).

Cheers,

Andy
