Filter by Steam Store Tags?

I'm wondering if it's possible to filter games by the tags from the steam store or other ways to filter by type of game. The reason I ask is that I'm wanting to filter the giveaways by visual novels without having to type in a bunch of specific ones and maybe find ones that aren't already on my wishlist. Is this possible in "vanilla" steam gifts? If not, does anyone know of an add in/chrome extension that could achieve this same function?

Thanks!
