Forgot to write [extendhopper.filter.set] in plugin.yml
Permission settings now work correctly.

Moving items inside Hopper now requires the permission [extendhopper.filter.set].

Improved handling of [shift + right click] in unnamed hoppers.
Improved chunk information processing when executing [reloadfilter] command.
And overall code optimization.

Fixed behavior when [Shift+Right Click] is performed on an unnamed Hopper.

Server logs now notify when a new version is posted.

Add the command “reloadfilters”, this command will re-detect the Hopper in the surrounding chunks[x32] and reload the config.yml.
Permissions “extendhopper.reload” is required to run the command.

The problem occurs when none of the custom filters are present. It seems to be an error because it returns 'null' when it tries to load the custom filter.
If none of the custom filters exist, it now logs “No custom filters found in the configuration.
This fix should make for a much better user experience!

Thanks!!

Added log display function and permission settings. Permission 'extendhopper.filter.set' is required for filter settings.
A log is now output when filter settings are changed.

Fixed, Filter settings may not be saved.
Fixed, Filter settings may not be loaded properly.
Other, minor optimizations.

When a player changes a filter setting, it is now immediately noted in config.yml. This allows for more real-time response.
We expect this to improve the user experience.

Dropped items are now filtered for pickup.
and,
Minor changes including optimization.
