Dev Build 2109 is out now.
Indent guides have received some more tweaking, and the default color is now less bright. There’s more control over the rendering via the indent_guide_options setting, with it now possible to configure old style vs. new style active guide rendering.
One setting for indent_guide_options that was almost the default is:
"indent_guide_options": "draw_normal", "draw_active", "draw_stack", "normal_stippled", "stack_stippled"]
This draws the innermost active indent with a solid line, helping to differentiate it from the other highlighted guides in the stack.
There’s also a new global setting, close_windows_when_empty, which is enabled by default on OS X. This closes windows when the last open file is closed, unless there’s a folder open in the window.
