I have recently installed this plugin.

github.com/SublimeText/Inactive … /README.md

In the instructions it states that I can adjust the dimming factor by putting the following line in my preferences.

"inactive_panes_dim_strength" (default: 0.2)

But when I do that sublime cries…

Preferences use JSON (JavaScript Object Notation), which looks as follows:

{
    "inactive_panes_dim_strength": 0.2
}

Thank you! Good work on this plugin!
