About BlockLocker
From SpigotMCProtect chests, doors, etc. using signs. UUID compatible.
This plugin allows you to protect chests, doors, furnaces, dispensers, droppers, hoppers and many other blocks simply using signs. Once a sign is attached, only people listed on the sign can access the container. It uses no databases, all information is stored on sign attached to the protected block. So if you use WorldEdit to move a chest, the chest will still be protected.

Features
- Protect chest, doors, etc. simply by attaching a sign.
- Doesn't need a database, the plugin just looks for attached signs.
- Allow other players to access your protection.
- Allow groups to access your protection.
- Groups are defined using permission nodes, scoreboard teams, or using supported plugins like Factions and Towny.
- UUID support
- Players can change their names without losing access to their protected blocks.
- Stores UUIDs on signs in an invisible way, so UUIDs are saved between server restarts.
- Players can change their names without losing access to their protected blocks.
- Supports double doors and double chests (double trapped chests too): you only need one sign to protect both blocks.
- Shows a message to players placing a chest, so that they know chests can be protected.
- Automatically closes doors when a [Timer:X] tag is added, or when a default door close time has been specified in the config file.
- Automatically let protections expire if the owner hasn't logged in for X numbers of days. (Disabled by default.)
- Redstone support
- Redstone contraptions cannot open protected doors, unless a [Redstone] tag is added.
- Hoppers (minecart hoppers too!) cannot take or put items, unless a [Redstone] tag is added.
- Update notifications
- Server owners get notified when there is a BlockLocker update available.
- The update checker works asynchronously, it will never block the server.
- The update checker can of course be toggled off.
- Configuration
- Add extra blocks, for example TNT, levers or note blocks.
- You can set that "attachable" blocks like levers can be protected by attaching a sign on the block the lever is attached on (no need to put signs on the lever itself!)
- All messages can be translated.
- Reload config files while the server is running using /blocklocker reload

Bugs
If you have found a bug, please report it! You can report it either on Discord or on Github. Please provide instructions for me how I can reproduce the bug. Please do not file bug reports in the review tab, as (a) bug reports aren't reviews and (b) the review section doesn't allow any interaction: you cannot reply there to any questions that I ask, so tracking down a bug is impossible.
