REQUEST: Simple Tags

If the module is not generally interesting,
I ask for a custom quote

I need a simple possibility to create tags for a Product in the administration.
The Tags i want to seperate with a KOMMA ( "Tag1, Tag2, Tag3, Tag4"). I thing the Position should be under the "Meta Tag Description" - also the new field can be use for "Meta Tags".

These Tags should be showed in the front-end-product-card on a free chooseable position.

A Click on a TAG should be show ALL Products with the SAME Tag ...
i think it shoukd be possible to make a simple search and also use the normal SEARCH-Funktion
