Getting started 1.21.11
Your first launch, the in-game menus, the HUD editor, profiles and cosmetics on 1.21.11.
The mods you will only find in Sour Client.
From the installer to your first world: signing in, picking a profile, the welcome tour, and the three choices it asks you to make.
Where every mod lives in game, how topics, search and favourites work, and how to open a mod's own settings.
Open it with Right Shift, drag any widget, snap to guides, and set colours for every widget at once.
A profile holds every mod, setting, keybind and HUD position at once. Keep one for Bed Wars and one for Duels and swap in a click.
What each of the three performance modes changes, which one to pick, and how your own tweaks override them.
Every Sour Client key and what it is set to out of the box, and where to change them.
Equip what you own, see it on your player, and choose which cloaks you see on other players.
Sour Client's own friends list and messaging: add friends by Minecraft name, chat from any server or the title screen, and control who sees where you are.
Make the menus bigger or smaller, pick the font, change the accent colour, and control animations and backgrounds.
Pack previews, faster pack switching, hiding packs made for other versions, and tweaking a pack without editing it.
Numeric ping instead of bars, coloured by quality, refreshed on a timer.
