Have you guys ever thought about having a simple document manager as part of the TP system?
For my last major trip I had about 50 bookings (flights, hotels, trains etc) and I had these all printed out in duplicate and stored in two folders that I carried with me for the entire trip. Whilst great, if I lost my bag etc, all my bookings would have been scattered around dozens of emails with various versions of bookings etc confusing things.
An idea came to me that it would be great to have a central point so that I can access all the documents (mostly PDFs) in a single place, and I thought that TP would be an ideal place for this.
It does not need to be very complicated. Create an itinerary (eg, trip to India). Within that itinerary, add dates, description and documents (eg, 01/07/2012, fly to Delhi, bookingABC123.pdf attached).
