Goodcompany,
You can turn of the autosave feature in the Admin CP. There’s a hidden config value that enables and disables autosaving of your posts on the publish page. There are a couple of ways to set it, but you can do it straight from the control panel. First, login to your control panel. Head over to Admin -> System Administration -> Config Editor.
You should then see a list of lots of config values - do be careful here, because you could easily break EE. Scroll straight to the bottom row where you can enter a custom key. In the first textbox enter autosave_interval_seconds. In the second textbox enter ‘0’.
And there you have it! Autosave will be disabled for any posts you’re editing. I’m hoping that EllisLab allow you to do this from the CP directly in 2.1.
Hope this helps,
Jamie
