I'd like to setup BIS lists for multiple specs and easily view this information on tooltips as the items drop.

In order to do this currently, I have to open the config and change the active list in order for it to update, or consolidate my lists into a single one

Is this a technical challenge not worth doing, or does this makes sense?

It should be that way thats a bug :)

EDIT: Ok waite no bug you can activate a list to always show in tooltip, maybe I should add a better option for that

I would honstly just change it to be active by default. Most players think it doesn't work because they can't find that option.
