Can you please add an option to be able to add a ':' after the hours plugin? Thanks!

The only addon that let's me put a READABLE clock in the top right corner of my browser (since Mozilla killed FoxClocks).
I just really wish you could set it to 12hr instead of 24hr.

Is it possible to make a 12 hour format option?

The extension is great, but it lacks the shade change with a click!
