Changelog:

⭐Add tweens to characters: fade in effect, use character icon to trace movement path
⭐Add globals.gd autoload which stores characters and a few globally accessible functions (Signal-Receiver system for ui elements only would be better, this should only be for data)
⭐Add Focus Mode - When enabled, only show characters in the area this character is located in. Multiple characters can be focused on.
⭐Add "toggled_focus" and "toggled_visible" signals on the character ui element
⭐Add back the button to display or hide invisible characters
⭐Add tooltips for all character list buttons
🐛Fix speakerArray having the FOLDER NAME added AFTER display name, resulting in FOLDER NAME taking priority in the interface instead of the other way around

Prerequisites

This tool currently only works on KFO-Server codebase, which includes the Killing Fever Online server that I host. Support for other codebases is considered, though it will need significant code overhauls.
You must have a GM client that has the option /remote_listen ALL enabled. Using that will give you full, complete logs of the entire session in every area. You can find your logs in Client Program Folder/logs/Server Name/2025-07-21 22-12-49 UTC.log, as an example - the log date and time is from when that client was first opened in UTC time zone.
