I have an idea for a new Smart Tag called an Aging tag!
For example I was updating a family album of photos that had older relatives.
Now I created a birthday tag for their birthdays but I could not remember how old they were.
So I thought it would be great to track how old someone or something was by having a smart tag that when a use entered a date and / or time that it would like at the system clock for the current time and date to generate on the fly years, days, & minutes old the tag was.
This could be used to track age of people, work, and things of files created!
