/pet who leader, /pet report buttons in pet window?
 

I'm an Enchanter. I liked some of the UI ideas for a minimalist pet window. No sit/stand, no taunt/notaunt, etc...

However, I also use the /pet who leader command to alert my group or raid that I have had to Charm something.

And I use the /pet report health command fairly frequently to check what spells are on my pet.

I have not been able to find a comprehensive list of hardcoded button functionality. Any ideas on how to go about adding these buttons to the pet window?

look at the default ui pet window - those all the controls available. Skinners can move stuff around and pretty it up, but we can't change core functions. So if the button you want isn't there - then you're out of luck.

I been thinking about your problem...
 

I do believe I have a solution for you...if you took the socials tab of the EQUI_ActionsWindow added a pet health bar, got rid of most of the socials buttons, and just put in one button for each of the pet commands u wanted, I do believe you would have yourself a fully functioning pet window, with customizable buttons. Im really not sure if this'll work, Ive never tried it, but it seems to be the only way to customize buttons...kinda.
