It will be nice if we have something like calculating the date where we have or when we use a date of birth date field, since in some cases we need to know the age without doing it with a calculator or asking for the age to them, this should be a smart system, but some of the features are very old technology and there are a lot of fields without any point to use them. just in the future as a recommendation, may be it is not important but i think this will help a lot.
