Do you want your wiki to have 3-10 different layouts?

I suggest there can be a layout implementation guideline, that includes

  1. layout should have at least a button including $:/core/images/default-layout or $:/core/images/layout-button, so a user can go back to the default layout on mobile
  2. shouldn’t add layout’s shortcut button to page control, instead, use plugins typed “Layout launcher” to launch them.

I think a simplest layout launcher is a toolbar like Page Control, but only shows layouts. I’ve developed at least 4 layout plugins, I sometimes imagine an Android launcher or Windows StartMenu for them.
