- Changes to handling & documentation of Runnables passed to ViewAnimator#Animate
- Got rid of unnecessary shadowing of controller field in a few Android*UI classes
- Moved clickView() out of CollectorController and into CollectorView
- Introduced usage of Activity#runOnUiThread() in a couple of places: these resolve known cases of exceptions being thrown if in the future we start running more code (notably "click actions") off the main/UI thread (currently not yet the case)
