[XB] Thread Reply Whitelist: Invite-Only Thread Replies 2.0.1

This add-on allows you to restrict replies to selected users only, keeping important, sensitive, or high-signal threads clean and focused - without fully locking them.

Ideal when you want discussion, but only from the right people.

Features​

• Custom Whitelists: Create per-thread reply whitelists to define exactly who can respond.
• Permissions-Based Control: Node-specific permissions to manage or bypass whitelists (own threads or all threads).
• Default Behavior: Enable reply whitelisting by default for new threads at the forum node level.
• Bulk User Addition: Add multiple users at once using a simple username list.
• Inline Moderation: Manage reply access directly via inline moderation tools.
• Batch Updates: Apply whitelist rules to multiple threads in a single action.
• Admin Tools: Search threads and filter thread lists by whitelist status.
• Custom Thread Icons: Visual indicators with configurable icons and colors via style properties.
• Member Limit: Set a limit the maximum number of invited users per thread.
• Invite Alerts: Notify users when they are added to a thread whitelist.

Useful for​

• Announcement threads where only staff or approved users may reply
• Support topics with a controlled list of responders
• Private or semi-private discussions without creating separate forums
• High-quality discussions that require strict participation rules
• Read-mostly threads that still allow limited, approved interaction
