Intellij enables multifile changes, renames, file moves with multiple files as single operation, as well as reload from disk, which breaks this simple linear history model afaiu. There is also a separate linear time-based local history in case you screw up. How intellij handles this is the best, in my mind, because of simplicity and separate "I screwed up" mode.
"Local history" in IntelliJ has saved me several times. The diff mode is very useful when working on a piece of code and suddenly your tests starts failing and you need to find out what changes you made in the last hour.
