MailSlayer is a Chrome extension that plugs in to your Gmail account to add apps that are inline with your Gmail workflow.<p>It started off as a Customer Service Application called Ticketive, but after we got a lot of user feedback from our Beta, we realized that people were using it way differently than we first expected.<p>MailSlayer is 100% modular, so you can choose the apps you would like to use and are not forced to use any apps you don't want.<p>The goal of MailSlayer is to make email better by adding useful apps into your current Gmail workflow so that you don't have to go to another website or service to manage these tasks.<p>MailSlayer provides a platform for developers who want to add functionality to Gmail, taking care of user authentication, data storage, DOM manipulation, and state tracking (with observable events when the user opens a folder or an email, starts writing a reply, and more).
If they can save me from having to re-invent the wheel when it comes to writing a gmail plugin/browser extension (especially threads and events), then this is potentially very exciting.
Used Ticketive for a bit, looks like it could be a solid competitor for Rapportive/GMail itself, especially if third-party developers start contributing functionality.
