Clickthrough v1.2

Configuration Update

This update adds a configuration file that can be reloaded with /clickthrough reload, so no need to restart your server. The configuration allows enabling item frame / sign clickthrough separately, and the no-permission message when entering the reload command as non-administrator.

Default Configuration Values

Enable Item Frame Clickthrough: true
Enable Sign Clickthrough: true
No permission message (%s is command, put "" for no message): §cUnknown or incomplete
  command, see below for error%n§c§n%s§r§c§o<--[HERE]

Clickthrough v1.1.1

Obstruction check for Shulker boxes implemented by @WMGameLive

Clickthrough v1.1

Clickthrough now works with signs as well!

And we (I) fixed a bug where you could still open chests even though they were obstructed. You can't anymore :(

Clickthrough v1.0

You know when you want nicely labeled storage, but your Item Frames always get in the way of opening chests?

No more!

Clickthrough allows players to simply click "through" item frames that are placed on chests, barrels, furnaces, etc. Basically, any block that has an inventory. Clicking on the item frame without sneaking simply opens the container the item frame is attached to. The item frames can still be modified by sneaking.

More precisely (and technical)

To be precise, players can click through any Entity whose type is or extends org.bukkit.entity.ItemFrame, given that it is placed on a block, of which its BlockState (block.getState()) is or implements org.bukkit.inventory.BlockInventoryHolder.

Client Side Alternatives

If you are just looking for a client side alternative, there is a fabric mod clickthrough.
