[anacreon]

So, parameters menus compared (titles in French, since I'm not sure what the English version is).

Compte (singular in 2.9, plural in 3.0):
pocket inserted, autres options suppressed and autorisations d'Adobe, which was "not connected" is now "not authorised"
Luminosité etc.:
a new line that allows turning off the statistics on the sleep screen book cover, which I hated (but they're still there on the off screen cover)
Pocket:
new line to dis/connect from that screen too
Paramètres de la bibliothèque (new menu):
to dis/able downloaded elements and covers in list style

I've also noticed that the dictionaries are now accessible from the home page bottom right button "supplements" but disappeared from the bottom right button when reading a book - I like it better the new way, but I suppose it depends on how you use it.

All in all, enough improvements that I'll install it on the Aura HD too.
