I see that this thread is quite old but as it's a sticky I hope it's still okay to post comments in here
I have an Aura HD but have recently found myself reading on my Nexus 7 tablet more and more often. Used in conjunction with a blue-light-blocking app like Twilight it actually makes for very comfortable late-night reading.
I was quite surprised however to find how many features were missing from the Android app, particularly since the Aura's formatting options are so wonderfully comprehensive.
Things that I think the Android app really need are:
Font selection
At the moment I can only use Droid Serif. There are ostensibly three choices (Droid Serif, Droid Sans and Publisher Default) but none of them actually do anything, I am stuck with Droid Sans no matter what (I have submitted a ticket regarding this but never heard back).
It would be great to have access to Malabar, Avenir and Kobo Nickel. From memory Avenir is indeed available on the iOS app.
Alignment options
I can't bear reading fully justified text, I much prefer left-aligned, ragged right.
Things that would be nice to have:
- Line-height adjustment
- Margin adjustment
It would be so great if the Android app got a bit of love, I have quite a big Kobo library and don't particularly want to shift ecosystems however I have started to buy books from Google Play instead because their font formatting options are better.
