Predefined waypoint creation
I very often record tracks of walking/hiking for OSM edits, and often it is needed to create a note for the position (as a waypoint) with really just the coordinates and some predefined data, like "bridge", "maxspeed 30" or "paths crossing".
It would be nice to be able to create a customised table (like an NxN matrix of icons or short texted buttons; preferably both the matrix size and the size of the buttons customizable, some people require only 4 buttons and others 25; probably making it scrollable would be useful as well :)) which could be invoked, one buttonpress and it would create a waypoint with the predefined data (like description, type, etc) and the table would disappear again, done. Fast, clean. (Probably along with record route activated.)
So I could walk, see a bridge:
1) switch on the screen (battery is my master)
2) press "open predefined waypoints table"
3) press "bridge" button
4) switch off screen
