Add Tertiary App and more

The Secondary App can be used in different contexts, double tap power button, bixby and now double-tap on the back of the device. As it stands, all of those options would trigger the same task.

A solution would be to add a Tertiary and Quaternary App if the others are in use. And seeing how new android versions and manufacturers could add more contexts, it seems to me it would be wise to let the user toggle the number of Secondary Apps they have on their system. This would mean less dev work when, inevitably, a new context is added.

Maybe add the option to rename the Secondary App in the App Drawer too, if it's possible.
