One thing I've noticed with the new EAP release of IntelliJ IDEA is a minor update to the subversion blame interface:

Ok, so this part of the interface hasn't really changed - but an accidental click on the revision number produced the 'paths affected by this revision' dialog I've fast come to love when I first found it elsewhere in IDEA:

It's a small change, but it's also somewhat handy. This may have crept in during an earlier EAP build but this was the first build that I found it in...
That's also for those little details that I love IntelliJ IDEA and why it
goes well beyond other IDEs in term of usability and productivity. I've
been "developping with pleasure" for several years already thanks to
JetBrains ;-)
