Here’s a script that allows you to allocate icons to each of your commands provided that the text for the command matches the icon in the script. There are, however, some scripts that this won’t be compatible with and it’s due to them using unique way of drawing out their commands. This script does not maintain compatibility for those specific scripts.
Go to the module and match the text under ICON_HASH with a proper Icon ID. You can find an icon’s ID by opening up the icon select window in the RPG Maker VX Ace database and look in the lower left corner.
— And that’s all, folks! —
