    I got frustrated with Gmail's lack of customization, and built an extension for myself. It doesn't do much other than modify how Gmail is displayed in Chrome.

    Hey guys, so I've been building my own Gmail for the past few weeks and would like your feedback. Find a preview here: http://i.imgur.com/UDz2y.png (Mouse cursor is over the "REPLY" button, to show the hover-effect) The app you see in the screenshot is what I've been using in the past week and it starts to feel better than the gmail interface.

    Hi everyone, My motivation for building this was to address the trouble of mass unsubscribing from unwanted emails and deleting bulk emails while ensuring privacy and control over the process. With this Chrome extension, emails are not sent to any external servers. All calls to the Gmail API happen locally on your device. Feedback and suggestions are welcome!
