Display pannels merge and easy to disaplay

[Green Cat]

Merging: just as merge chest mods do, the more pannels you have, they become 1 biger screen.

(the easy to display ->) and like this, if we merge let's say 4 display pannels horzontally, connect it, and open it, you can chose an item. Say item icon will be showen, if nothing (0 imput), said icon will show and 0. If there is, it will show the icon, and 3 digist since we merged only 4 display pannels
