I have developed the plug-in fragment which adds in JD-Eclipse an ability of realignment of a decompiler output. To use this feature it is necessary to open the menu
Preferences/General/Editors/File Associations and to select "*.class" file type and to choose "Realignment for JD Class File Editor" for Associated editors. Other ability is
batch decompiling of files of classes. To use this feature it is necessary to open the menu Preferences/Java/Decompiler/Batch Decompiling and click button "Open dialog".
Put a file realignment.jd.ide.eclipse_1.0.0.jar in eclipse/plugins directory.
