Apple updated the beta version of its Pages, Keynote, and Numbers for iCloud suite today with a few new features and improvements. Notably, each application will now remember the last document you opened and settings like which interface elements were enabled or disabled (such as alignment guides and the zoom setting).
The apps will also automatically suggest your most recently used nickname when editing shared documents, improved image masking, and keyboard shortcut hints in contextual menus. These changes—especially the ability to remember your document settings between launches—more closely mirrors the functionality of the desktop software.
You can try the updated web apps on the iCloud website. The full statement from Apple is below:
