I understand work has been going on for the iPad and iPhone versions (iOS8), but now that these releases are imminent, and in no way throwing any cold water on those accomplishments, I hope focus can return to the Mac app with some new feature development that Omni has stated is its full intention to implement once this iOS milestone is reached (common database format across all platforms).
I’d love for the bugs to get ironed out of the one-line view, promoting it from a beta/quasi unsupported view, to fully supported as I believe many of us rely on it. (Often defer dates simply get skipped when tabbing through quick entry or the main view).
I think user-definable metadata (tags, people, etc.) is pretty high up on most people’s lists also.
