Some of the scripts had been part of my daily toolkit, others have been added over time thanks to suggestions and feedback from users. It's important to note that this tool is not supported by Shopify so don't bother them with your support requests. This part should be obvious, but use this tool at your own risk.
The current version of the Chrome Extension has over 10,000 active users and will remain a continued work in progress. For a running commentary on the features and updates check the freakdesign blog or the thread on the Shopify forums. You may want to follow the public development on GitHub (which is also the place to leave bug reports), or follow me on twitter.
Not every feature, but some of the handier ones...
Inline Metafield Editing
No longer do you need to open another window to edit your Metafields. Everything happens within the dashboard, on the same page.
Copy Shipping Rates
Stores needing to ship to the EU can have a hard time creating all those shipping rules. Copy and Paste saves you time, more time for vodka.
Buttons have been added to let you add all or remove all tags. There's also a bulk tagging option for the lazy (aka: efficient!).
Install and Support Development
To help me continue development on this tool consider leaving a tip (especially if you've used this on a project you're charging for). To install the bookmarklet simply drag the Shopify button below your browser bar.
