Twas a joke sir really its personal preference and so I don't have to sell things one by one to know what I have and what to get rid of and overall faster maintenance on making sure my budget is I profit knowing even a little about coding knows it would be a small effort to add a remove all button just pass it along like you do everything else.
My lab from the upgrades tab says its getting +10% to combination then when I go to the lab to combine something it says +3.5% from lab so which is it? Also the vip function one level 1 says I can to levy twice a day as apposed to just one but its still making me pay gold for the second its a good thing I didn't put a lot of money into this game but I figured I'd post this to warn other players about spending their money in this game.
Needs a removal all in the stock pile choice list you don't want your gangsters running around trying to find their weapons gotta keep your list clean.
Your Mobsters will automatically take all of your best items into Fights, so no need to worry about keeping things organized. :)
