Google redesigned Presently and added the old-fashioned menu already included in the word processor. The interface have been streamlined and there's more room for editing slides. A notable new feature that can be found in the Slide menu is zooming in/out, but the keyboard shortcuts aren't very intuitive: Ctrl+Shift+left/right arrow.

It's no longer necessary to use bookmarklets if you want to add a table of contents in Google Docs because this feature is now available in the interface: Insert -> Table of contents. To add a table of contents, your document needs to include headings from the Format menu. You can find more information about a word directly from Google Docs: click on the Tools menu and look up the word in Merriam-Webster's dictionary and thesaurus and in Encyclopædia Britannica.

In the Tools menu, there are two other options that allow you to search the web for the selected text. It would be nice to see the results in a pop-up box and to link to them directly from Google Docs, but this is not yet possible.
