Extension Updater support
The most popular extension on this site is Time Somewhere which was helped greatly by @jdfwarrior‘s WolframAlpha extension. He also made Extension Updater which my shell script extensions now support (everything but Relaunch, Consider Unpausing and Windows Booter). Just install the Extension Updater extension and type update check to check for updates or update to check for and install updates. Check out his Tumblr for more great extensions.
