See, Lancer_325, there are no tighter margins. Moreover, it wasn't necessary to delete your only existing library. All you needed were two copies of Marvin at the same time, and you could have pushed the backup file between them until you got it where it belonged. For example, you could have made a backup from that mistakenly received iPhone version, too, then send it to (for example) the old Marvin for iPad (after reinstalling it just for the sake of temporarily storing the backup file).
I'm sorry it didn't work out for you,
but it was
not Marvin who made this complicated for you... App Store is to blame, having sent you the incorrect iPhone version, thus disrupting the quick & easy process of switching to the new Marvin version.
Attached is a screenshot showing
three Marvins
happily coexisting on my iPad currently: new universal Marvin, original Marvin for iPad, and Marvin Free. This allows me to have
three books open in Marvin at the same time.
