My suggestion is nothing more than some “sugar” as to achieve what I want without it is very easy but would make management of a Coda doc on an ongoing basis a bit easier imho.
To explain I have a screenshot:
I have summed up all of the values in a column of a table and outputted that value.
I then need to use that same summed value to make another calculation - in my screenshot above, I want to subtract the summed value (£343) from my total budget.
Of course, I can just re-enter the formula, but it would be super cool if you could define a computed property/variable which would give you the summed value that you could then re-use throughout your docs. Then, if something changed in that formula - you’d only have to adjust in 1 place.
Perhaps this variable would be “assigned” to the table (in my example, “Refurb costs”) so that one could access something like [Refurb Costs].totalAmountPaid.
