In the main screen dropdown that displays the quantity of adv resources and the quantity queued the quantity queued only shows the advanced resources queued and not the crafted items queued. As a result, sometimes queues look empty when they are not. Can you just have the display show the number of production hours left in the queue? That would account for the different production times for crafted and normal items as well as allow players to know more intuitively (as they level up buildings) when they need to address their queues.
Another thought to further condense that information is to just have a color shading behind each resource total that went from light green (for queues longer than a player settable time) to light yellow and then light red when empty (if production is possible for that resource). Then you could make that whole bar a little less intrusive and people could see their daily bonus.
