Speaking of the Documents view, I would like to see an option to view documents as a text list instead of just the grid of previews. It can be difficult to parse long document titles when they run past the border of the document's box, especially on the iPhone. Also, editing a filename means tapping the title on this screen, which is a small target on the iPhone. Currently the only custom viewing option here is to sort the documents by date or title.
A newer, better outliner
The big news about OmniOutliner 2.3 for iOS is its ability to run on the iPhone as well as the iPad, but it's worth noting a few welcome features that were added in version 2.0. There are settings specific to using an external keyboard with the app: using the Tab key to navigate between cells, showing keyboard shortcuts in inspectors, and typing Command-V to paste text styled or plain. The app can import text shortcuts from TextExpander if it's installed. And additional templates from OmniOutliner 4 for Mac are available.
Like the ideas you'll be working on, OmniOutliner 2.3 for iOS is evolving nicely.
