Dynamic Array Function Suggestions
The current UNIQUE function should be modified to align with industry meaning. For example, in SQL and also in the Power Query Fuzzy Lookup functions, UNIQUE has a meaning OPPOSITE to the Excel function. In both cases, UNIQUE refers to values that occur only ONCE in a dataset.
In addition, distinct should not be mixed into the same function. DISTINCT should be a separate function, which refers to values that occur more than once in a dataset (from which we want to extract distinct values).
Add a new TOPN function. This function would work independently of SORT (a function should do just one thing). An option would allow ties to be included.
The proposed modification to the UNIQUE function and the addition of DISTINCT and TOPN are natural feedback suggestions with respect to the new and unreleased Dynamic Array functionality.
