I use MDBG as my primary Mandarin dictionary, and Denshi Jisho (www.jisho.org) for Japanese.
One of the things I find incredibly useful is, at MDBG, the ability to click a link and have a new word added to my Skritter queue. I love this feature!
Are there plans to do something similar for Japanese? I'd love one day to find a "add this word to your Skritter queue" link among the options at www.jisho.org.
