I am on a touchpad. When I click add book I see a long list of books, mostly just showing the author name + 1 or 2 characters. the other 2/3 of the screen (right hand side) is blank. There is clearly room for another 75 or 100 characters.
Once added to the library the full author and title shows just fine.
I am guessing this is an artifact of coming from the smaller display on the phones.
Are you using the native version (v0.9.x), or the old Javascript version (v0.8.x). Because that decides whether the bug can be fixed or not.
I'll take a look at it anyway, and check if I can find anything in the current version.
