I just mean it's a completely separate app to the phone system itself. It will output an RPY file that's pre coded to be used with my renpy pone system.
It doesn't make any difference to the actual phone system itself, it's purely a way to speed up creating conversation and being able to visualize branching dialogue.
The phone itself comes with ways for the player to change the colours of the phone in game, but if you want to change them manually you'll need to edit the file directly. This purely creates an RPY containing the conversations and branching dialogue pre coded.
