The plugin allows you to insert your items into the sign by clicking the right mouse button. To pick up an item, you need to hit the sign with theleft mouse button. Items on signs can be waxed with honeycomb, once they are waxed they cannot be taken by anyone. Waxing can be removed by using an axe. This plugin also supports sign protection from plugins: WorldGuard, Lands, Residence, HuskClaims, GriefPrevention, SuperiorSkyblock2, ChestProtect and GriefDefender.
Hopefully this will improve and diversify your gaming experience.
If you are using CoreProtect (v22.0+) to view player actions. You can use the command to view the actions of putting and taking an item from the signs.

If there are any problems, suggestions. You can write them in my discord server. I try to take into account every opinion of the players of my plugin.
