Some improvements for StarWars's behaviour after onPause(), but it doesn't really work yet.
Remaining 'onPause-buggy' apps: StarWars, Save.
Some more tweaking to the 'Save thread.'
Fix the 'Save' app so that the saving thread does not run all the time in a tight loop
Fix the 'Save' app on Android API >=23 (we need to explicitly ask for write permission)
Tidy up 'Save'
Save the image to 'Pictures' album in the Gallery.
Move the 'Save' effect to the Application and remove the 'OTHER' effect queue
