The waitress who boxed up the leftovers not only marked the container with what was in it, but also the date. No opening multiple containers in the fridge to find the right box, and no wondering later "how long has that been there?"...
Very nice, thoughtful touch, right?
To those of you who sell digital products, particularly download-able products, are there any nice little touches you can add for your customers?
Things like naming zip files, folders, and product files with meaningful names?
Maybe adding file sizes and estimated download times?
What else could you add to make your buyers' lives easier and their impression of you brighter?
