I realize this is something that I may be out on an island on, but...
As a person, who frequently has Lower League Management Saves, where the Manager is a bit part of everything (Coaching, Scouting, Negotiating, Finances, etc), I would really enjoy seeing enhanced depth/control of the Financial Management component. Over the years I have been able to pretty closely understand the Profit/Expense line items and their origins--but it is not often intuitive. Understanding/managing these costs are crucial to LLM and very important in dealing with FFP. I would love for the statements to be more traceable/manageable, for budgets/projections to show where the costs lie, not just a number that says you are projected to have a profit or loss of $X. To be able to have input in determining ticket prices and have that determination have a real impact on attendance increases/decreases. To be able to have a Budget for Data and having spend impact quality/quantity of data returned. To know what the cost of requesting an increase in Youth recruiting is going to be and how it will impact the budget. Essentially, to be able to run a club that generates more profits and provides the Board/ownership more $ to invest in the improvements needed for the club. I could go on and on, but you get the drift.
