I have created a plugin patch for the VocabBuilder plugin.. essentially patching the "onDictButtonReady" function.
The problem i am having is closing the dictionary window upon tapping the "Add to vocabulary builder" button -- to save the extra "close" button tap to close the widget.
DictQuickLookup

nClose() crashes KOReader.
So.. what needs be done beyond the "require" for its module? Or is some other approach needed to close the dictionary?
