What might work is an app called Tasker, look that up im not even positive it works on the prime, or without root
essentially its a condition/trigger app
IF location is home, THEN set wallpaper to XYZ1
IF location is work, THEN set wallpaper to XYZ4
IF dock is detected, THEN set active keyboard Swiftkey
again not positive if it will work ..but if you want to do something, when a condition is met (docked/undocked) then this is the app for you.
