This optional flirting modification moves all of the flirting dialogue options to the upper left of the dialogue wheel. It also moves the friendly non-flirt version on the upper right.

With regards to romance, all romances are now opt-in from choosing the "flirt" option with the character you're interested in multiple times rather than being assumed from Shepard being friendly. This especially applies to Steve Cortez, who in the unmodded version requires MaleShep to be single for the game to head down the more romantic dialogue paths.

This also applies to James Vega's scenes, where a FemShep can be friendly and get the Lola nickname without all of the flirting that usually comes with it.
