Unmaintained Day Night Switcher 1.0.0 (RC 3)

Great addon!
I bought the swift theme with day and night mode.
I am a novice but with this addon I can switch the themes of my users without problem.
Very easy to install and use.
Simple and effective, I recommend

Great addon, does what it says it will do. I will give it another star if you can make more time periods possible instead of just a day and night. It would be great if I could select a new time period and choose the style to switch over to in that time period. This would give me the ability to have morning, afternoon, sunset and night time.

Very nice add-on, does exactly what it says. My only suggestion would to have the user's preferences dialogue be a drop-down, and let them select 'Day/Night', 'Dark', and 'Light', so that the user can choose if they want they always want the 'dark' version for example if that isn't the default outside of this add-on.

It is nice.
It would have been nice if there was a button for users to manually select.
Can you do that?
