Wokabulary 6 wil have a special filter to easily find all duplicates and synonyms in your vocabulary. So you can more quickly cleanup your words or practice synonymous words.
By the way, Wokabulary won’t add or import exact duplicates of existing words. But that only applies if both sides of the word pair match letter-by-letter.
Will I be able to add a synonym on the run when adding a new word? Like a button “add synonym” which immediately opens a new word window and copies alle the information from the previously added synonym like tags and translation.
