Graphic UI showing 4D table for sorting hand variants used in switch layer
Click to select switch layer, alt-click to select another switch layer.
While switch layer is selected use table to see (mouse move) and apply (mouse click) any of sorted switch children.
Click on upper table levels walks your to the deeper one. Watching and appliing is possible on the last level.
To go level up click on the right icons showing selected levels to deselect it.
Select switch child layer in Moho Layers list View to setup the table (to set a cell for each child)

UPDATES:
v. 1.2: added Vertical Flip button (for display hand icons)
v. 1.3: adapted for Moho 12.x versions (was compartible with 13.5 only)
