If someone's hunting for Biosphere gear or something, or just farming for Heirlooms, a command telling you the amount of quests you're still able to claim would be nice. I know that upon completion, the NPC already shows 'you can complete this hunt X more times", but there's no way to know that other than doing the hunt again only to see you can no longer claim rewards. (If there's any means for that already, I'll delete haha). So theres @cooldown for instance reset times, I'd suggest a command that shows a list of that, but instead of reset times, keeps track of how many more times you can claim rewards.
