Depends how OF for iPad is architected, especially around that button, but the + has a few different uses for new Projects, Folders, project or context specific actions and inbox actions.

Omni may be planning to expand it's usage, for example OF may in future allow nested projects, so in all future versions, I think that the + will be multifunctional.

There's nothing to stop a toolbar being introduced though, that may be a better request.
