@jim_chapman I found out this was in the app a while ago, that's quite fast 
I've been testing it for the last couple weeks or so, and think I might have found some bug.
To reproduce the bug:
1. go to any book, use `This Book` preset to save some settings for this book
2. go back to bookself
3. quit the app
4. reopen the app, and observe that all the settings in the app seem to have been reset to defaults (e.g., background color, control settings, etc.)
If I open the book with its own preset in 1., those settings are still applied - just that now with the 'base' settings reset to defaults, the overall effect is different.
I suspect that when a book's preset gets applied, the base settings it applied on top of is lost in a way that it can no longer persist till the next run of the app. Maybe there needs to be a hidden 'base' preset, which gets updated whenever any settings get changed, that can then serve as the starting preset to use on app load... (that's just my 2cents)
EDIT: I retract my words - I've somehow 'fixed' my problem. I was scrolling my book list and found a book called 'settings'. When I opened it, it showed something like a xml. I deleted it and now I don't have the same problem if I follow the same steps above... I'm not sure how it ended up there though. Anyway - thanks for getting this feature implemented! It is super useful to me
EDIT2: I retract my words again - the problem has reappeared after a reboot...
