I love onedrive and have been a long time user since it was called skydrive. I also love the sharepoint features in onedrive.
But I stopped auto saving by default. I find that simply navigating a document and making markups ends up saving the document when all i wanted to was view it and not save it
I use the modified date filter extensively to figure out what is most relevant and what is not. With autosave, the date modified keeps changing. And going online and restoring the file to an earlier version changes DM to now. Meaning that information is either permanently lost or I have to hack it and change it manually.
