--EDIT--: The dev has updated their addon to allow the option for a 12 hour clock. Thank you so much!

--[Original review]--
I would love the option to switch to 12 hour instead of 24 hour, but otherwise this is very functional and eyecatching. This addon doesn't require any unneccesary permissions either, which is a win in my book.

wish it wast in military time

I wanted a simple, readable at a glance, Toolbar clock, This is perfect. Thank You.
