I am learning both Japanese and Chinese and there are a few things in the Chinese dictionary I use that I would really love to have here:
1) One of the hardest things when learning Japanese is figuring where one word ends and the next word begins, so it would really help if we could look up a group of words. So for example, if I searched γγγγι£γΉγ¦γγΎγ, instead of getting a "not found" message, I would get entries for each word in the same order they appeared in the sentence:
γγγ
γ
ι£γΉγ
γγ
You can see how this looks by searching ζεζ¬’θΉζ (I like apples) in this Chinese dictionary: https://www.mdbg.net/chinese/dictionary
2) Another feature I really love using on that Chinese dictionary is the text analyser. You can try it if you go on the link I posted above and click on "Look up All Chinese Words in a Text", then on "Inline / popup annotation", then on "Show only Chinese inline - details in popup". When you copy and paste a text there (you can try it with: ζεζ¬’θΉζ), you can then practice reading and just move your mouse over any word to quickly check the pronunciation and meaning (and if we could also see the meaning of the kanji it would be even better). You can also click on any word to open the entry in a new tab for more information.
3) It would also be very practical if we could copy and paste from the search results. I like adding new words to a vocabulary file that I use to memorize them, but it takes more time if I have to click on the search results before being able to copy the translations. Also, it would be nice to see the meaning of the kanji directly in the search results, either on the right side of the entry or by moving the mouse over the kanji.
4) When the dictionary finds no results, it would be helpful if it could suggest words that sound similar. To avoid affecting the quality of the results, you could just add a line of suggestions at the bottom, under the actual search results. Something like, "Did you mean: SUGGESTION 1, SUGGESTION 2, SUGGESTION 3, etc."
And you could show suggestions as we type in the search bar, like Google does.
