I really, really would love to see the design of Thesaurus: Synonyms 4 Right Click (https://chrome.google.com/webstore/detail/thesaurus-synonym-4-right/lpkpcliecpgjbkffooidajhakoidhidh?hl=en) integrated with this database. I hate that this has an extra step of the popout or additional tab whereas the other one has a terrible database, but great user interface.
