There have been some other request about functionality related to columns, but this one is (I think) just a bit different.
It would be nice if, when opening the column properties, we could edit the name of the column. And if we can edit the name, it would be even nicer if we could use a formula or combination of a formula and characters to specify a name. The formula could reference a canvas formula plus some fixed data (text, number, symbol), a row in a table [table].column.nth(1), etc. The latter would make it possible to control the table column names from a central table, very nice for quickly styling tables, forms that are based on those tables, the tables were the results are processed, etc. Many changes with one edit!
