xplr layouts define the structure of the UI, i.e. how many panel we see, placement and size of the panels, how they look etc.

• custom

The users can switch between these layouts at run-time.

• { LengthLessThanLayoutHeight = int }
• { LengthLessThanLayoutWidth = int }
• { Max = int }
• { MaxLessThanScreenHeight = int }
• { MaxLessThanScreenWidth = int }
• { MaxLessThanLayoutHeight = int }
• { MaxthLessThanLayoutWidth = int }
• { Min = int }

      vertical_margin = 3,
      constraints = {
        { Percentage = 50 },
        { Percentage = 50 },
      }
    },
