Generally speaking, everything seems to work as expected, though I found a few nuanced issues (aware that it is still Alpha).
* Filters work, I did not notice anything that did not filter properly.
* It would be nice to disable certain filters (eg: let me filter specifically on Ability Type without needing to have everything else On).
* Searching works but appears to be case-sensitive.
* Search does not filter out non-relevant results (eg: Princess puts Princess Huhuran and Princess Yauj at the top, but also displays all other pets underneath, in no particular order). Not sure if this is the intended result.
* Adjusting Filters overwrites the current Search field, requiring the user to click back on the Search field and either add/remove letters or press Enter to reactivate the Search field.
* Sometimes when opening, in the 3D model pane, the Pet Icon and Ability Icons are not loaded (blank) until you click on one of the pets. Have not been able to purposefully replicate it out of reloading the UI, which I sort of expect that to happen since it needs to reinitialize or whatever. This is a very minor issue, but I thought I'd mention it.
I'm curious to see Beast Squad in action, assuming that lets players quickly swap between active pets. Sometimes you're in a thematic mood or maybe you just want to mix things up a bit.
Overall, a very nice add-on, that is visually clean while presenting relevant information. Great for Hunters with a lot of pets (I only have about 50

).
