Redmine

In an attempt to make time tracking easier for people in my office, I created a time tracking add-on for Firefox.

https://addons.mozilla.org/en-US/firefox/addon/redmine-timer/

Feedback and bug reports are welcome. A brief description is below:

A button in your browser to start/stop time tracking.
If you're on a Redmine issue page when you start tracking, it tracks time for the issue. If you're inside a project page (but not inside an issue), it tracks time to the project. You can also use a keyboard shortcut (Alt + R) to start/stop timing.

A page full of your projects
Some people don't always work on Redmine issues (like account managers) -- they need an easy way to jump from project to project and track time. If you go to the main Projects page in Redmine, you'll see a link to add any project to your "Timer Buttons." There's also a link at the top of the page to open your list of timer buttons.

When you open the list, you'll see a touch-friendly list of those projects. I move this window onto my laptop screen (as opposed to my main external monitor) so I can simply touch the one I want to time.
