ZDT
Zhongwen Development Tool - helping to study Mandarin Chinese
...The most important feature is the flashcard study feature.
ZDT currently contains:
* a Flashcard plugin for memorizing Chinese characters, their meaning and their pinyin/pronunciation. The user is able to import Character lists or enter them manually. This
* a Dictionary search plugin with three dictionaries: ADSO, CeDict, HanDeDict. The HanDeDict is a German dictionary. It is also possible to search any word lists entered by the user using the flashcard plugin.
* an Annotator plugin. The Annotator converts the Chinese characters into pinyin, using the Alphabet with accents.
