Thanks for the reply sampppa - TBH I think the program is very useable as it currently is. Like I said audio alerts, full HeiaHeia editing (like mood etc) and it would be complete, so great work.

N900 + Zephyr have been working very well.

Just out of interest, I also manually upload to Endomondo but it seems none of the heart-rate data is processed, not even max or average and am wondering if it's to do with the gpx format?

Off-topic: I find HeiaHeia much better at keeping track of exercise activity, and meeting weekly targets. Whilst Endomondo is much much better at logging personal bests, averages, calories burnt and routes taken. So I find both essential.
