[FR] Add &tags to TaggerGetRelatedWhere snippet

[nick2687]

As a developer of an e-commerce site who uses tags to organize products,

I would like the ability to display a list of resources that not only share common tags with the current resource I am viewing but also have a requirement that the returned resources contain one or more specific tags so that I can create more contextual related lists.

This could be done by adding the &tags option to the TaggerGetRelatedWhere snippet.
