2. How to disable auto-save:

There is no way to switch it off. The option 'Save file on frame deactivation' in the 'Settings | Appearance&Behavior | System Settings' provides ability to make sure that a frame really will be saved, but frame will be still saved if the option is unchecked.

Disabling auto-save feature discussion:

We don't support any 'on-save' actions due to the way the IDE saves changes - actually it reserves the right to save any of your files literally whenever it wishes(smile) You don't have any guarantees on when RubyMine flushes document data displayed in the editor to file system. E.g. it is allowed to do that while the document is being edited - automatic code formatting would be rather annoying then.

We have a feature request for 'on save' actions -, please feel free to vote for it.
