One feature I’ve realized it would be really nice to have is the ability to ignore basic typos when typing pinyin into search. Like if I type lsng instead of lang it could know to search for lang because s is next to a, or even more simply: search for l*ng because it knows lsng is not valid pinyin, maybe with a set of options to choose from (lang, leng, long, etc.) I’m not sure about the technical complexity of implementing that though.
