The way I (a bisexual) have always interpreted the difference is that pansexuals feel the same attraction to all genders and that bisexuals feel different attraction to different genders. I identify as bi because I definitely feel different kinds of attractions towards men, women and enby’s.

I stopped using it because apparently it had been abandoned by the dev, and switched to Infinity because it’s extremely similar, but I loved Slide too. Will definitely use this.
