Reworked the Investments Tab. Now you can properly buy/sell/update your investments to keep track of your Profit & Loss. When creating a new Investment, first of all, you will be able to select what kind of asset this is (It can be Stock, Crypto, ETF or Other). After creating an asset, you can buy/sell/update your asset. When buying, enter the quantity, price per date and set a date when bought. After buying you will instantly see your new updated portfolio value & how much you have invested. If you want to see your Total Profit & Loss, update your asset prices.
