I need to add some buttons to trigger functions from my stock management module (currently in development). I'd like to put them in the backoffice, somewhere like here
I think I need a display hook, linked to a function which in turn calls the functions I want to trigger.
I also think I need to edit a tpl file in order to display the buttons.
Question: Which .tpl file should I be looking at editing for the products list screen in the back office?
And, assuming this is the proper procedure, how do I make it so that this .tpl file updates with the new buttons on a Prestashop installation?
I'm guessing there's some sort of override run from the module itself but I haven't figured out how that all works.
