Extension sync comes to Google Chrome
It's not enabled by default, so you won't see it in your sync options menu unless you activate the feature via a command line switch. --enable-sync-extensions --sync-url=https://clients4.google.com/chrome-sync/dev turns it on (again, see our tutorial on using command line switches if you're not sure how to do this).
Today's dev channel release also brings the usual assortment of bug fixes and tweaks, but extension sync is by far the biggest news. Hit up about Chrome in your wrench menu to auto-update, or head over to the download page for Google Chrome's dev channel builds to take the expanded sync feature for a test drive.
Thanks for the heads-up, Logan!
