These are few of the tools and extensions we use to make working with Google docs much more easier, the only missing feature we see is a sync utility for Google Docs. Previously mentioned DocSyncer did have a sync feature for Google docs, but sadly they have closed shop and entered the deadpool. Are there any other tools you use, do let us know through your comments.
