Google Docs added some enhancements to presentation application:

-Multi-shape formatting allows you select multiple shapes and/or text boxes, and format them all at once. Hold down Shift key while you click each object, or drag over all of the objects that you'd like to select.
-Text boxes now grow in size as you type and you can now vertically align the text within multiple boxes using a new Text Vertical Alignment button in the toolbar.
-Now you can better navigate to specific slides within your presentation, click Start Presentation button, then look for a toolbar at the bottom to immediately jump to a different slide.
