I think users will fin useful to have their expression per layer, so
they can refresh a field with the same calculation, without the need to
rememberwhich formula they used (very stupi example: refreshing the AREA
field). In this way, a DBF can be used almost like a spreadsheet.
For advanced users it is probably useless, for newbies it can save a
loto of time, effort and frustration remembering which expression they
used, what is the exact syntax, where (if) they copied the expression
somewhere, etc.

All the best.
