When editing most tile types, the device name is displayed in the editor. For example, this is the editor window for a switch tile. The name appears just below “Tile Editor”:
However, when editing a variable tile, the device name is missing:
If you have more than one variable tile with the same appearance it isn’t possible to know which tile you are editing. For one example I have tiles that use up / down arrow icons but no header text.
Include the variable’s name in the tile editor window.
