Tagscape for Datasets/Flows

I've seen a lot of people asking about a folder structure for datasets/dataflows however, it seems like an easier to implement approach would be to add a Tag field to datasets/dataflows.  Just like there is a text field for a description their could similarly be a field for tags which would be searchable.

Sure, we can currently do this with naming conventions, to a degree, however the names end up messy (and readability is dependent on screen width) and the order of the elements in the naming convention becomes incredibly restrictive.

Being able to tag a flow with "Dev" or "Production" or "Needs Optimization" would make life much easier as an admin.
