If you go to the attendee or order list we do have an option to print a list. Its formatted nicely to print on any size sheet and will allow you to cross people off at check-in. We also export attendees and orders to CSV so you can pull it into Excel and format it to your specifications.
The other features we are hesitating on because we aren't convinced that people really need them. Doing less, but doing it significantly better is what we are aiming at. We realize that we will not be getting the really large events to move to us, but they are not our target market. We are aiming for the smaller events that don't have professional planners that take care of everything.
That said, we have a list of features that we think we need to add. We plan to add most of them before we exit beta. Features on our list include a public attendee list, ability to ask for custom information per attendee, and uploading of custom background images for events.
