I really love the boosters but it is so hard to get so many gems and then the booster lasts for 2 days.

Any chance we can get half boosters for half the number of gems?
I'd also love to see a booster that would speed up growth time. For instance, instead of it taking 18 hours for silk, 9 hours.
Pick the crop you want to speed up or all your fields in half the time

Also any chance of getting a notification like the popups for the factories showing at the mine how many pieces of equipment you have to use?'

Can we get a button that wouldn't cost anything to get the planes in faster?

Last could we get a popup on the barn that shows our empty space?
