better than a printed guide, but also limited by them

This app is great for scheduling which events at a convention you plan to attend, and for looking up descriptions of those events with a single tap. But most cons guides are otherwise just scans of their paper guidebooks - you can look up a list of all the exhibitors in the dealers room, but most of them have no description (because theres no space for them in the printed guide and the digital version apparently wasnt worth their bother) and the app cant point out where their booth is in the dealers room because the map is just a plain image. It seems obvious that you should be able to add your own custom events to your "My Schedule", but instead theres just a "To Do" list whose entries dont appear in your schedule, or even have reminder alerts.
