TL;DRAllow the player to click and drag items in their hand crafting queue.
What ?In the image above, I'm hand crafting 19 speed modules. This is going to take some time... but I urgently need those 5 stack inserters. I'd like the option to click and drag those inserters to the front of the queue so they are built before the speed modules. Since the stack inserters are dependant on the fast inserters and gears, they'll come to the front of the queue too.
Why ?How many times have you queued up a whole bunch of things thinking "I'll hand craft this while I do other things", only to realise you need 3 inserters immediately. Now you have to destroy your queue, add 3 inserters, then recreate the queue.
Or am I the only one who queues up hundreds of science packs?
