Just uploaded the new version with all this in, also adds the volume of them to the settings screen of the phone. There's a few extra checks it does for messages appended using functions as well.

Quick question. Is there a way to set up contacts so that they only show up in the phone once you reach a certain point in the story? Like, one at a time? For example, the mc gets a new phone, meets a person, they give them the number, and then it shows up on the phone. How would I set this up? Currently, in my code, all of the text conversations are showing up on the phone, but at this early point in the story, there should only be one contact, not all 13. Sorry for bugging you again!
Sorry I just noticed you'd messaged again. When you create the conversation using the kps_create_conversation() only add them as a member, then use the add member function (its in the newest release) to add your mc to it later, it will instantly appear on their contact list :) You can create a conversation with 0 members if you want, theres nothing stopping you, but the second a member name == a phone name, the conversation will appear
