Agent's Pack of Coolness

This is literally the best vanilla Minecraft client-sided pack you will ever see. This modpack is a massive collection of a ton of quality-of-life mods and resource packs. This pack is mainly for bringing back the original feel of Java edition as the main version of Minecraft(such as using VanillaTweaks to bring back the original blue-tinted buttons and remove the Java Edition title), but it can be customized however you like!

(A side note is this pack includes two resource packs that I've made and posted on CurseForge that are enabled by default and make the game fell more like it used to. Shameless plug. Sorry.)

I've pre-included some configurations for mods like BetterF3 that make sure it won't get in the way of the minimap, but again, feel free to customize this modpack to your liking. 

Installation:

This modpack can be installed via the Modrinth launcher, the Curseforge launcher, ATLauncher, Prism Launcher, or literally any other launcher you can find. Easiest method would be to install it using the Modrinth launcher.
