I realized that one of the things I like about writing on paper is the ability to arbitrarily position my text. Is there good software for OS X that lets me put the cursor anywhere I want and begin typing immediately? As for PCs, I think OneNote allows this — is there anything else? What about software that also lets me drag and drop entire blocks of text any way I want to organize them?
