Talkgroup ACL editor
Each slot can allow all talkgroups, deny all talkgroups, or allow a specific list. Saving changes updates the HBlink4 JSON config but does not alter passphrases or pattern matching rules.
Full configuration backup & restore
Download another complete backup at any time, or restore a previously downloaded HBlink4 config after a rebuild. Restoring replaces the complete config and requires an HBlink4 restart.
