Absolutely right Lee. Stylesheets are usually not changed, but core files, controller files and templates files are often changed with upgrades.
That is why you still see some folks running .5 or .6. They have made extensive mods to their cart and don't want them undone with an upgrade.
just to be sure you understand - that information is in the database and if you or some one you hire wants to change the coding on the style sheet to show those additional fields you can do that. But it is not a cart function switch currently.
Do remember that any code changes you make may be overwritten when you update with new versions. So if you change a code, know where and what you did and then check on the new version and see if you need to make it again.
