JSON editor for Eclipse

Simple and handful editor from  http://sourceforge.net/projects/eclipsejsonedit/ , however installation was not that obvious. 'Install from zip file' did not work for me. It was sufficient to unzip content and copy 'plugins' and 'features' content to 'plugins' and 'features' folders in eclipse installation. Works for me :) Checked on Eclipse Inigo and Spring Source Tools Suite.
