<I guess Name Manager by Charles Williams and I will have to fill that gap once more>
Yes please! If you could scope the work to allow any named formula to developed (from scratch or by modifying an already defined formula) using some user-specified scratch space on the worksheet, that would be of great value. Ideally the upload process should accept the cell formula from working formulas or the cell value if the name is defined as a text string. The characteristic of LAMBDA that makes it different from existing formulas is that the parameters would need to be omitted from the defined name.
1) Although it may be expected that many named formulas will now be moved to the LET function with single-cell scope, there is the possibility that the LET function may itself appear within a named formula, greatly increasing the complexity of the defined names one may wish to create.
2) I have suggested working within some designated space on a worksheet simply because I assume that will be far easier than developing a form that supports IntelliSense and can display dynamic arrays; the latter may well be impossible
