I like to program at day with a light- and at night with a dark color scheme. Because of that I’ve decided to write this little plugin, that switches automatically, based on the local time, between two predefined color schemes. Moreover there is a keyboard-shortcut (Ctrl+Super+S) to switch between the schemes manually. For more information, please read the description at (https://github.com/KLINGTdotNET/ColorSchemeSwitcher).
I hope someone will find it useful, too.
