Visual filters for those who don't know Hebrew/Greek

I recently discovered on these forums a guide for creating a visual filter to highlight the second person plural pronoun in both Hebrew and Greek (creating my own "y'all" version, if you like). This filter is really helpful in sorting out when the author has a group in view versus an individual.

Are there other visual filters you would recommend for someone who doesn't know Hebrew and Greek, so that one could see at a glance something basic and important about the text? 

For that matter, any other helpful visual filters even if they aren't related to the original languages?

Thanks!
