Marketpress more product details

Hi Aaron
Thanks for the replies.
I would still like to add more product information.
Model, colour, manufacturer, location (GPS, long, lat, country, state, city, suburb, postcode)
Is this feature able to be included in the next update? or do you want us to edit the code?
If so, I am just wondering that would mean in order to keep the plugin updated I would have to manually insert the changed code every update? How does it work...
Cheers
John
