CheckmarkBan
by Maleccki
CheckmarkBan adds a clickable green checkmark after online player names in chat, opening a configurable menu of player commands on click.
What it does
Chat messages are scanned for the names of online players, and a bright green checkmark is attached to each one. Left-clicking a checkmark opens a management screen with buttons that run commands predefined in the configuration file. Each button can send a command message, and placeholders such as player and player% are replaced with the username of the selected target.
The mod is a Fabric client mod for the 1.20.1 – 1.21.11 range, with files for 18 release versions. Only the client needs it, so it works on vanilla, Paper, Spigot and modded servers without any server-side installation. The code is released under the MIT License, and the project is not open source.
Key features
Clickable chat checkmarks
Green checkmarks are appended to chat names of online players, and each one can be clicked to open the menu.
Configurable command buttons
Buttons and the commands they run are defined in a JSON file, with message templates for each action.
Target placeholders
The player and player% placeholders are replaced with the name of the selected player when a command runs.
In-game config reload
Changes to the configuration file apply after running the reload command, without restarting the game.

Use cases
Moderation on multiplayer servers
Staff can send their usual commands to a player from chat, such as checking a player or sending a warning, with one click.
Quick actions in chat
Players can start a trade or friend request with a name in chat without typing the command by hand.
Who it’s for: Players who spend time in multiplayer chat, and server staff who run the same commands on many players. Because it is client-side, it suits players who join servers they do not administer.
