to delete names you have to edit the javascript file (.js) there you have an object name_tag, it's a simple if. if (the message isn't from us) then (name_tag = "sender name or whatever you like") else (name_tag= "You | ") i simply removed that if and just set name_tag = "" then, for the timestamp color, just edit the html and css, and delete the secondary color from it (secondary color it's in color.css and belongs to the theme, so if you change the theme, changes the secondary color, this way a conversation theme can adapts to every theme) then i just create a new class named timestamp that has color:#000, this way it doesn't matter which theme we use, the timestamp color will be always black
