Thanks for comment
Right now you can edit only for ver.1.5
Please vote if you'd like to implement such feature.
for now i know i can edit single items, but not in mass features and also import product with such database fields.
Because of that i am voting to make this happen and so that i can use again store manager for my eshop.
Thank for understanding... hope you will do this soon.
