The In-Tray is a great little creation of Dominic that can help you remember anything from chores that you want to do around the house that day to questions you want to ask during an interview. The In-Tray is a very simple 10-15 location journey that you can put information before hand in or information on the go. For instance, you can research ahead of an interview and put in questions you have about the company/position or you can add questions to the journey as the interview is going.
Another really cool thing you can do is break down your resume/cv into key points and place each point into a location in a journey, so if asked to recall a certain time in your life on your resume, you won't get stuck saying "ummm", "ahhh". The versatility of the In-Tray is basically endless and I'm sure you could come up with many more applications.
