Add filed to grid to see product type: parent or child

It would be useful to be able to have field in product grid, that could show which product is parent and which is child. Also, then it would be possible to filter products in order to see only parent products or only child ones.

Please vote for this feature if you would like to see it in future releases of store manager for VirtueMart.

Your further comments and suggestions are welcomed!

Thank you!
