i am looking for something like this for ages!!! it is so obvious but nobody has done it yet - visual and audible notification on any screen you are in rr (for poi or any other coordinates). it would be even better if not only approaching in angle or distance but keeping the direction and route you are on to give you a notification (what about garmin mobile pc as underlying gps nav, which is the best and most accurate in laptop market).
i prefer visible notification (big red flashing) since it takes my attention while driving and listening loud music (audible beeps blow my speakers and ear out).
do you say you have a working solution or only the skins ready?
there is something similar already built-into rr but never seemed to work and i don't know if you can have those popup boxes like you show on your screen shots. it is in the "native reminder function" thread.
