Thought of a few more questions...
5) For Moon+ Reader or Pocket, any thoughts, recommendations, preferences on use of A2 mode, "Bleaching function," "Use Regal to refresh," or any other settings that can be configured on a per-app basis? I think I understand A2 mode, but I'm a bit fuzzy on Bleaching and Regal as to when I might want to use them, and what the pros/cons are of using them (eg, using more battery?).
