Two days ago I uploaded my first plugin to the repository at WordPress.org. It is called Whereabouts and lets you enter your current location and time (+ time zone) and display that information as a widget.
You can see it in action right above this post. (At least until I post something else.)
I built it for myself primarily, but thought I should actually polish it a bit and share it, so that – maybe – someone else would find it useful. So there, you can download Whereabouts from WordPress.org.
Feedback is welcome. 🙂
