I am new to the Ipad 2. My main goal in getting it was to be able to easily carry with me my multiple To Do lists. I need an app that has an organizational system similar to Windows Explorer where I can have notes inside multiple folders within folders. They need to be able to be easily moved about & reordered. I don't need any fancy bookshelves or covers. They just need to be easy to see & see what is inside of each folder if you want. They need to be able to expand & collapse. I need it to work off-line. Please help. I have already spent about 10 hours searching the App store & the internet. i have already tried Evernote, Meteor, aNote & FileApp & they don't do it.
