I´m a fan of Capitalism since 1995 but still not an expert in making decisions. So I thought about a improvement for me and other Players.
I would like to suggest a "forecast" for one single Business. If you select a Business like a factory or a retail store and press a specific key like CRTL+F (or click a button from the UI) the game should freeze the screen at the actual date and time like a Savegame. Now the time should run at highest Speed and You will not be able to do other Actions then watching the changes in the selected window or cancel the forecast. If you cancel the forecast the game will go back to the origin date and time with no changes.
Background of the idea: I often don´t know if it is better to build a new purchase/sale/manufacturing unit to react on Events. This will bring a great help to newbies. you could think about a fee for every Forecast or link it to HQ-functions. Additionally you could implement a coincidence/random factor for every day the forecast is running so that the result is not 100% correct and you can run the forecast a couple of time (expansive fees!) to get a reliable Information.
Of Course this should not work in the stock market and YES, it is a quick save and quick load in one fuction.
Please excuse my expressions, I´m from Germany.
