This ties in with recommendations of others where they recommend changing the color of the filter button to easily identify filtered columns. Also consider providing drop down option or pop up option to list column names (with alphabetical label of column, such as (A), (B), etc). This will help to easily identify columns where filters are applied. You don't necessarily want to go to each column, but rather want to catch up with the logic / thought process you were busy with. Maybe some short abbreviated info about the values filtered as well.

Money in Excel should allow manual entry of older transactions so that the whole year's transactions can be contained in 1 sheet. Right now Money can only import about 90 days of transactions and January and February are missing from my transaction log.

Now we can do that for current worksheet only. These days it's quite desirable to have an option to keep greedlines off on permanent basis for each new workbook. That could be done using template or by changing/adding registry key https://www.quora.com/What-are-some-ways-of-removing-gridlines-in-Excel-2007.
That will be much more suitable if we have such option in Advanced section of Options.

There should be a Paste Special option to paste formulas without updating relative references.

Corkscrew accounting is fundamental to Financial Modeling. It is where opening balances are carried over from closing balance of prior periods..

=OpeningBalance(FirstPeriodBalance, PriorBalances)

Where FirstPeriodBalance is the first period's opening balance and PriorBalances is an array of closing balances for each period.

The cell containing this function will return FirstPeriodBalance. The SPILL range will contain the n-1 closing balance array value.

I'm proposing that header argument be added to the FILTER and UNIQUE Dynamic Array Functions just like we have seen in the STOCKHISTORY function

Say you work while traveling on a train. Someone wants to know who you are for whatever reasons. If your name is in the title bar of an application or the user name on the logon screen, giving away your credentials that easily... User credentials should not be disclosed in title bar of office applications and there is really NO sensible reason to show them on the title bar. Fancy true, safe nope. Remove it.

Would be great to have a way to monitor the usage of an Excel File. working in Finance, many of the reports we produce can be used or not used. having a mechanism for a file author to get usage statistics would be super helpful. for example each time the report is being opened it pings the server and let the author know through a report sent weekly or daily (customizable).

Money in Excel should show due dates, statement balance, and minimum owed for debts (e.g. credit cards and loans). Somehow it could track if debts are on "autopay" or paid already for the next due date (or allow the user to specify these).

Text to Columns Wizard - Select multiple columns when changing Column data format

On using the Text to Columns functionality, you can change the Column data format (step 3 of 3). You can only select one column at a time and set the format. It would be great to select multiple columns and change the column format to one specific format in one go.

Can you add a budgeting function to the template Money in Excel? Tracking my transactions is great, but being able to assess if they align with a monthly budget would be ideal.

Create a function called ArrayJoin() or ArrayConcat(), this would join two or more arrays together to make one array. This could be used on spreadsheet directly or embedded in inputs of other functions eg to dynamically organise inputs for MMULT().

To be able to pull data from the Egyptian stock market using the Stock Data type and the STOCKHISTORY function

Hope to see data from Singapore Stock Exchange available in the Sock Data.

Create a budget template to make sure you aren't spending more than a certain amount per month in a budget (e.g. shopping, dining out)

Currently XLOOKUP can return an array of return values, given an array of search values, OR a range corresponding to a single search value. Like other functions, it does not return an array of ranges but, rather, truncates the calculation.

This may have been acceptable in the past when the expectation was to copy formulas across to return values that logically form an array. As dynamic arrays receive increasing use, the expectation will change and the failure of a range to spill will be far more problematic.

currently the amount of characters allowed per tab is 31 maximium. THIS IS NOT ENOUGH. please make an option to extend the amount to at least 100. If you do this you are good. If you don't you are bad. It is that simple.
