Is it possible to search for a word within a course(or the library), to find all of the uses of that word? It would be very useful to have instant access to multiple uses of a word, instead of waiting to find them by chance in random lessons.
Japanese has a very complex word-form system for verbs especially, and it’s difficult to process learning them without multiple examples and context. But other word forms can be difficult to understand also without having several examples of usage.
