I was hoping for a Vendor Feature. Unlike just a tooltip with a name and how much the pet costs. I was hoping for something close to the Rivals Tab.

First, it would be its own tab. "Vendor"

The left side would have the list of all pet vendors (with gold or charms or tokens). The Right Side, would start with the portrait. The lower section would be controlled by the top buttons (like with rivals). The buttons at the top would be Vendor Items (Click to show pets sold by the vendor and cost), next button location (similar to Rivals) showing where the pet vendors are on a map. The third button might be notes on the vendor (such as some have unlocks or quests to access or faction specific).

Having the search bar at the top left would be good so if you wanted to find "White Kitten", you could type it in and Lil' Timmy would be filtered. His notes might include Spawn information or route.

A filter option would be nice for seeing vendors by Gold/PetChrams or Dungeon Tokens, reputation, expansion or other options, "missing pet from".

The main goal is on a slow day, I can open my journal and see which vendors I can buy pets from, decide if I should use gold or my charms. Find the vendor on the handy map, and then go on with my day.
