When I have a lexicon, or other original language resource open, there is an "active" box which, when a lemma is pasted in, it is found in that resource if that word is covered as a topic. Typing in is possible too, if I change the language in windows to that original language.
For example, using Liddell and Scott's lexicon, a Greek lemma finds the article where the word is discussed.
I think it would be helpful if those boxes were set by default to the appropriate language, so that typing "allos" in the box would automatically display, "ἄλλος."
If this has been suggested before, I apologise for the repeat. I haven't found it, though.
