Plugin category: Building / Redstone Minecraft version: 1.13 What I want: Prior to 1.13, I used a fantastic double doors plugin called "GtzDoors." You can find it here: https://www.spigotmc.org/resources/gtzdoors-double-doors-and-door-knock.37517/ It's pretty simple: You open a door or trapdoor (wooden or iron) either by hand or by redstone, and the adjacent door would open, but only if they were "facing" each other (so 2 doors with the knob on the same side wouldn't open, but two doors with adjacent knobs would). I'm wagering the flattening and removal of item IDs in 1.13 finally killed it. It hasn't been updated since Mar 2017, and I can't get in touch with the Dev. While searching for a 1.13 alternative to GtzDoors (looked for about an hour, tried a couple that no longer work), I found another great little doors plugin called Secret Doors, found here: https://www.spigotmc.org/resources/secretdoors.2570/ This poor relic hasn't been updated since 2014, but the idea is absolutely solid: You place blocks in front of your door, and you can open the door through those blocks, which will be replaced when you close it. There's a great demo video on that Spigot page for it. I'd love a 1.13 updated plugin that combines both aspects. They really are fantastic little additions.
