Dupe-highlighter

A Chrome extension that finds and highlights duplicate transactions on Mint.com's Transactions page.

Go to chrome://extensions/
Turn on 'Developer mode' if it's not already (switch in top right corner).
Click "load unpacked".
Navigate to your project in your file system and select it.
This loads it in your local Chrome browser. You should see the favicon in your toolbar and in the //extensions page you'll see a card for your extension.
Load changes by clicking the reload icon. Do this every time you save in your text editor and want to see the changes in the browser.

To update, in chrome://extensions, click refresh on the individual extension card. You may need to refresh the browser too.
All of the functional code for this app is in content_script.js.
