At the moment, it is quite clunky to establish what is currently being built and to see when a Hearthling has stopped crafting due to missing resources or an empty build queue.
Here is what I propose:
Add a persistent icon for each crafter on the HUD that displays the task being completed or show if a crafter is idle and also highlight when production has halted. A way this could be accomplished is by highlighting the border of the crafter’s icon red to alert the player that the crafter cannot continue. You could also consider adding text that shows what resource is missing.
Crafting items is such an essential part of the game and when a Hearthling is idle or cannot continue crafting they will potentially not be gaining experience and be holding up other progress in the game.
I realise that perhaps not everyone would want clutter in the HUD so you could consider this as an option to toggle on and off in the menu
I’d be interested in a response to see if this is consistent with the direction you’re taking the game or if there is other development in place that would make this unnecessary.
