I'm still amazed that Apple is still so entrenched in this whole Autosave/Versions thing. An OS that gets in the way of what the USER wants to do is bad design.
Now, there are quite a few things shouldn't really be a choice. Gatekeeper in ML and other security built in to OS X to keep malware off the system is always good. It still has its limits, but it does a good job. And as it should be, you can turn it off. Case in point. Yesterday I went to install i1 Profiler in ML. It stopped me and said it was an unsigned app and wouldn't be allowed to install. That, along with a message to visit the System Profiler to make any necessary changes. I did that and changed the setting (temporarily) to allow all software. Then I could install i1 Profiler without issue. The point being that if Apple were as stuck on Gatekeeper as Autosave/Versions, I wouldn't have been able to install very expensive, very necessary software. At least for now, and maybe always, you have to have a way to disable it.
You can list a lot of grunt work the OS does without your knowledge all the time that you neither need to know about, or have any reason to change, and that's all good. But, the OS has no right at any time to force you into a specific type of workflow. It's sole function in that respect is to do what the user wants to do, not the other way around.
Much earlier in this thread, I wrote the following:
If it were that great, would there really be 226 million pages on the subject? The majority trying to find out how to turn Duplicate/Autosave/Versions off?
That was a typo on my part. It was 226 thousand, not million. However, there are now 179,000,000 matches to that search. Granted, as you get deeper into the listings, any match in such a phrase without any quotes will return any page with even only one of the words in it, which may not have the slightest thing to do with OS X. But a very large share of the earlier hits do. Within those are many more users responding on the various pages asking how to turn Autosave/Version OFF.
Shouldn't it mean something, anything at all to Apple that a very significant percentage of users hate this function and are looking for a way to kill it?
