First of all, a big thanks to all developers who create such a wonder piece of software for all of us.
I wonder if Goldendict already has this feature but I don't know how to do it in the preference setting, or it is not yet there. That is, for example, the word "games"; does Goldendict knows how to truncate the ending-s and check for the word "game". Of course, the same feature should include handling of ending-ed, ly, etc.
It is especially useful when using Scan Popup. You click the word, instead of editing the top-left box most of the time, one gets the result needed instantly!
