Description of the problem / feature request / question:

Sorry, I have some silly questions here.
There is no .leptonrc file in my home directory. How do I change the appearance of the whole interface into dark mode? I tried to use the Developer tools to change the color and I met these two questions:

1. After I changed the color and close the application, the interface returned to the light mode when I reopened it.
2. When I finished the dark background and grey text color changing, the syntax highlight was till fitting the light mode, I couldn't see the code clearly. I'm wondering how I can change the syntax highlight color theme.

If possible, provide a sample gist or screenshot:

If possible, provide the log files

For Lepton after v1.9.0, the path of the log file can be found at Command/Ctrl + ,

• Mac: ~/Library/Application Support/Lepton/logs
• Windows: C:\Users\<username>\AppData\Roaming\Lepton\logs
• Linux: ~/.cached/Lepton/logs

The debug mode is recommended when producing the logs.
You can send your log file to cosmo.lepton@gmail.com if don't want to post it here.

Oh, you have to create the file yourself if you want to further configure the app.
