Thanks for your reply Stefan.
I am VERY happy to hear that you are working on adding the custom products feature. The day you add this feature will be the day we begin the upgrade process. I really hope it will be ASAP.
When it is added will products that have been added manually in V1 appear in our store after we upgrade to V3?
I am asking this because I don't want to add 1,000 products manually to our store today (which takes hours and hours), only to have them disappear when we upgrade in a week or two.
