Custom Interface - Lines Should Disappear
-
to speed up the interface design, the lines on the interface should be removed and only the design should be displayed when hovering the mouse in the settings section. (optionally, it would be better if this feature can be turned on and off)

in this way, it is not difficult to see the result of the design because of the lines overlapping on them while creating the design. it is not necessary to constantly preview. the process can be accelerated.
when the mouse comes back to the interface screen, the lines reappear and the user can freely select the desired area.
