Open files in read-only format by default
One of the reasons we chose to use SharePoint was the ability to control sharing and editing. It used to be that files were opened in read-only format by default. A few months ago, this seemed to change.
All files were being opened in editable format (unless specifically saved to open in read-only format), with changes being saved automatically. Autosave can be turned off easily, but only for individual files. Consequently, each time I opened an older file to check something and made minor changes like hiding a column, the file would auto-save before I even realised it, causing havoc with the "last modified" info.
Please bring back the default read-only mode!
Agree with what JC said!
Would be good to be able to control this for Groups of users, and at a folder level ... and maybe tie it so the only way to get into edit mode is to check it out, otherwise it's read-only (this avoids the issue of checking a document back in and then having an un-constrained edit happening... you can roll back to the check-in version but if you pick it up and make edits then you can end up with undesirable changes that are not properly tracked.
Interesting wrinkle - if you apply the "ReadOnly" option within Powerpoint (for instance) but then run a macro which makes a temporary change to the presentation you get an Access Denied error, *but* if the file is marked as 'read only' as a Windows Permission you can still run the Macro (but just not save updated permission) so might be nice to have some granularity - either apply the Office "readonly" or the filesystem level

This is a no-brainer. Office online is unusable without being able to open in Read Only by default, and then allow those users with permissions to switch to edit mode. You should also be able to do "AutoSave" functionality like in the Desktop app. O365 should track a user's "drafts".
Does Microsoft even use this? Totally agree with LastModified. It is so frustrating when someone contacts thinking that I am the owner of a document, because I simply opened a spreadsheet and used a filter. Stupid!
