This allows two columns to be in sync. After installing, configure the columns to sync by entering in their respective project ids in the plugin drop down from your chrome browser.
Note: this currently only sync's story data. Tasks, comments, blockers, etc will not sync automatically.
## To get the project ids for the source and destination fields:
grab the project Id from your url. For example:
https://www.pivotaltracker.com/n/projects/{PROJECT_ID}
## To link a story
Next, any story you want sync'd needs to have the story id in the description of the source story.

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
