Sleeve, my focus right this moment is creating various replacement lockscreen including one that sticks to minimal and retains slide to unlock plus full customization of when/how the lockscreen will wake up. That's been the plan since before I wrote one line of code. I even plan to port the exact layout of stock lockscreen as an option, just with music controls and other utilities as options.
When the idea for this app first hit me, it was the desire that my waiting messages would display on my lockscreen. From there I've built the design from the ground up to make progress toward the realization of that functionality.
