Easiest way to trinketswap as a hunter in classic (Itemrack)

Excuse the sound and picture quality, this is filmed on my laptop.
Download Itemrack (and trinketmenu for easier access and overview)
www.curseforge....
Open up the itemrack addon, chose the "queue" tab
Chose your trinketslot, select "use" trinket on top, passive trinket second and then stop the queue.
Tick off "auto queue this slot"
Pop your use trinket - wait for the duration - Pet passive - Feign death
It will automatically swap your passive trinket in, so you get the utility of both trinkets instead of wearing an empty slot for the rest of the fight!
This applies if you have two use trinkets too, just queue the second trinket slot and make sure you USE both trinkets before FD :)
