I completely understand this frustration with WHMCS client management. In my experience managing multiple client accounts, the inability to bulk update client groups has been a recurring headache, especially when launching targeted email campaigns or reorganizing customer segments. Having to update clients individually is incredibly time-consuming and prone to errors. This feature would be a game-changer for agencies handling hundreds of clients. The current workaround of exporting data and manually updating through the database isn't ideal for most users. When taking breaks from such tedious tasks, I sometimes unwind with simple browser games like Italian Brainrot Clicker for quick mental refreshment.
