Context
I want to work on the sidebar layout, but have lost track of where it's used.
Some layouts are in a custom Mantra Layouts module.
Questions
How can I check where a layout is used? (including multisite)
Findings
Implicit grid columns can be used to break out the sidebar from the layout.
TODO
Get a handle on where layouts are used.
Improve sidebar layout.
Done
Find layouts in use: grep -rni "layout_id: mantra_layout"
Removed use of mantra_layout layouts.
Use --sidebar-first-width variable for min width. Set with UI Skins.
