This is an extension for the 5E rule set to add a column at the end of the Character Sheet Inventory tab to allow players to track which items they have attuned. I found no way to track this easily within Fantasy Grounds, so created the extension.
Thanks to st4lk3r87 for providing an update to the extension that adds an option to change the attunement limit from 1 to 10 within Options and also enforce the limit on the inventory tab. The default value is 3.
Thanks to Valerian for providing an update to the extension that correctly handles deleting an item and updating the total attunement count.
Compatibility
The extension should be fully compatible with other extensions since it employs a merge join.
