However, my interest in this feature is not simply to have an auto-backup of dirty editors, I'd like to be able to entirely remove the concept of explicitly-saving (and of dirty editors as a consequence), but instead implicitly save editors to their original files, not to a temporary copy somewhere else. IntelliJ follows this behavior.
So, I've originally posted about this here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=34076#c89
, but I'd like to bring up this issue with a wider audience that just those listening to the bug. Especially with regards to how this relates to Auto Building, and the question about the usefulness of Auto Building (please see that bugzilla comment).
