i thought it would be really convenient if the compendium - lets say you click on a kapura - at the bottom could show which wolf(s) have that companion attached to them. it could be just a text list of names or little icons, they don't really need to be clickable but it would be handy if so. i find myself having like 5 of the same companion, and like 100 wolves, and it's a little hard to sort thru all of them to figure out "which one has this companion attached?"
i'd also find it very helpful to have a counter somewhere on the page telling you "how many of this companion do you have attached?" ("you currently have 12 shadow kapura attached to wolves")
