Whenever there is a screen where your backpack is on one side and there is another storage area on the other (shop sell menu, cache, box, etc) a button you can click to just move an entire stack to the other area would be amazing. I have 100 strawberries, I have to move my mouse over to grab them, then go back to the sell area and place them there. If I could hold CTRL or ALT + left click and they just plopped over that would be amazing.

Regarding categorization, I'm sure something is planned, but a quick sort button (based on object type, name, colour, whatever) would be very helpful for both storage and backpack areas!

Thanks guys!
