In the edit window for lingqs you could add little coloured boxes to colour the text to represent the gender of nouns in languages that use genders, for example:
pink - feminine
blue - masculine
grey - neutral
Then over time when people are adding new words they would automatically be colour-coded from when people did them before....assuming everyone colour-codes them correctly of course! :)
I use a colour-coded set for German vocab with Anki and it makes remembering the gender of nouns so much easier!
