Cover Flow View
It would be great to have coverflow in landscape mode, specially when there are photos in the forms. The photos could flip with a tap, to show the rest of the field entries. There can be a limit to the number of fields shown. And for forms without any photos one could customize which fields they want visible in coverflow view and also the ones they want to see when it's flipped. The way there are different icons for different forms, there could be different form themes/types to choose from.
This will make viewing and navigation easier for the chosen fields and will be visually better too.
One thing I love about the iPhone is Cover Flow and I would love to have it in Tap forms coz I use Tap forms extensively.
On second thoughts, flipping could show all the fields, with scrolling.. or by turning it back to potrait mode.
