Passthrough Signs - Transparent Signs
This mod adds a convenient feature that allows interaction with objects through wall signs. Now you can right-click through signs to open chests and work with other blocks that are usually obscured by signs.
For example, if a sign is attached to a chest, you can open it immediately by clicking directly on the sign - no need to remove the sign first.
Starting from version 2.0.0, the functionality has been expanded and now also works with banners, item frames and paintings (these options can be configured and are disabled by default).
The mod must be installed on both client and server for proper operation.
