There was an xposed app that allowed me to access widgets while the lockscreen was securely locked (so I can start music without having to unlock the phone with a pattern or pin to access the music app). It was called "Samsung Multiple Widgets". It does not work for any ROMs above 4.3.
I'm now on Hyperdrive 17.1 (using 4.4.2) so it no longer works. Does anyone know of a replacement that will allow me to have that same functionality?
