The default modpack loads the game with Minecraft's default settings, while the express modpack loads the game with my personal settings. I do not like forcing my preferences onto other players, but I also understand starting from scratch can be a pain, hence the option.
Notes:
Zoomify is bound to "C" by default, which needs to be changed as it combats with the creative mode "Save Hotbar Activator" key bind
Light Overlay is bound to "F7" by default, but has no conflicts
Chunks fade in currently does not work while Nvidium is active. To turn on chunk animations, Nvidium needs turned off
Please note that all mods with custom config changes are listed at the bottom of this changelog
