I'm planning on taking my partner and his family on a trip around the UK next year, and I have a ton of ideas in my head that I want to have written down in some form that makes it easy to edit and move things around. So I'm looking for suggestions for software that ideally makes it easy to enter information about transport and hotels, as well as thoughts on potential destinations, day trips, etc. I have used TripIt, but it requires me to be a bit too specific with dates and times, I want something that is more flexible and lets me brainstorm without pinning me down to certain things.
Thanks for any help.
