Hi Mike,
Thanks for the question. The way that my autosave feature works is similar to how Microsoft Word does it. While you have your document open and are working on it, TodoPaper is saving your changes to a separate file. The document is an "active" document and not necessarily the final saved version. The autosave feature is mostly used in the event that the application or your computer crashes and you haven't saved the document fully. When you open the file, ToodPaper will ask you if you want to restore to the backup (autosaved) file. Now, some people said it was a little bit confusing the way it opens the autosave file and not restoring it to the original file. So, in the next version it will be a little bit more clear.
Please let me know if you need anything else.
Thanks for your support.
best,
Jordan
