Dear developers,
Your game is awesome and addictive and I can sing praises in your honor for hours.
But, it appears to be lacking a very fundamental option - click and hold in the production queues or the bills.
If I want, for instance, to smelt metal slags until I have 1000 pieces of iron, I have to click 1000 times on the small plus sign instead of just clicking and holding and watching the numbers rise.
I believe this will greatly improve the UX and make billing/queuing more accessible.
Sincerely,
The bear that don't care.
If you click details on the queue, you can go in and adjust by 1, 25 or 250. You can also set minimum / maximum crafter skill, qualities, etc.
