for example:
the Program asks only:
  Sales on VAT 25%   = X
  Sales on VAT 5%     = Y
  Sales payed by Card = Z
to enter predefined values at:
  Sales                     = (X*100/125)+(Y*100/105)
  VAT in 25%             = X-(X*100/125)
  VAT in 5%              =  Y-(Y*100/105)
  CASH                     = (X+Y-Z)
  Card Commision        = Z*1,25%
etc.

(I know that VAT is computed automatically in FrontAccounting -depending on sales- but i use it here like a simple example)

It would be e usable enhancement of the new 'Quick Entry' feature (which ask you only one variable to entry and compute only percentaged values).
