The tabifier plugin retabs Java code so that syntactic elements are aligned vertically.
Version 4.3 handles array initializers better, and provides an option to disable array initializer formatting completely.
Version 4.3 also fixes a problem with class-level comments, which were being aligned with field declaration trailing comments. Any comment in a class (or after the class, e.g. after the closing right brace) which has no preceding text or which occurs before any declarations are seen, is considered a class-level comment and will be left justified.
Download with plugin manager or at http://www.intellij.org/twiki/bin/view/Main/TabifierPlugin. (There's no difference between version 4.2 and 4.3 except for the Plugin Manager change text, so get version 4.2 at the wiki site.)
As always, please let me know of any problems.
