Version: (using KDE 4.3.1) Installed from: Ubuntu Packages It would be awesome to have a possibility to kde return if the system is working in good configuration and save the actual system like a restore point to use for system fail recovery. This option would be in grub to load last known configuration like windows do.
Could you be more specific which configuration you are talking about? Most configuration items that could render a system unusable (system packages, init scripts, X11 driver setup, etc.) are out of KDE's scope.

This is a thing you can get with btrfs snapshots and snapper. It would indeed be nice if there were a KDE project that provided this functionality, but it's kind of out of scope to request a whole new app in the bug tracker. :)
