Oh my gosh! Words cannot express how helpful this plugin is to me! It is so nice to be able to read articles AND! If you use the "shift" key when highlighted over a compound kanji you can analyse EACH CHARACTER! You can get the key words for each kanji singularly AND also get the NANORI (name) readings! There are three dictionaries to switch in between from (using the shift key). This plugin is really seamless! I HIGHLY RECOMMEND that you learn how to use the controls for this plugin n the options menu for it. The short cut keys make using it way more useful and easy! :D I am indebted to the developers, thank you very much!
