Managing Applied Stickers
You have access to the list of stickers of a surface, of which you can modify the order, the transformation, and the name.
This function is available via the contextual menu of the selected surface. Right-click on the surface then select surface, Edit the properties, and then select the sticker tag.
Tip
To click on a surface, the surface must be visible. Display all surfaces by right-clicking within the viewport and choosing the option, Show All (Ctrl+Shift+R)
The sticker placed at the top of the list in the Stickers manager is the one perceived in the foreground in the active view.
The up and down arrows 
allow you to change the layer order of the stickers. Select the sticker and click on the arrows according to the desired arrangement.
You have the possibility of renaming the stickers by entering a new name in the input field located at the bottom of the Stickers zone.
The U and V Offset and the Rotation parameters of the Transformation zone allow the sticker to be placed more precisely by entering numerical values directly or by using the keyboard cursor arrows.
