Mountain Toolkit: Professional Profiles

Professional Profiles is a lightweight, client-side Fabric mod for Minecraft 1.21.11 that lets you save and auto-apply per-server and per-world options.txt profiles so your settings (including most mod keybinds and even resource packs) stay exactly how you want them everywhere.

Features

Automatic Profile Switching

Server Profiles

• Automatically applies the best-matching profile when you join a server
• Supports multiple servers per profile

World Profiles

• Automatically applies a profile when you load a specific singleplayer world
• Useful for “hardcore,” “creative,” “recording,” “testing,” etc.

Mirror Global vs Override (Per-Setting Control)

For each setting, choose:

Mirror Global (default)

• Always uses your normal global options.txt value

Override

• Profile forces a specific value

This lets you make profiles that only change what matters (like FOV + sensitivity) without duplicating everything.

Profile Manager (In-Game)

Adds a Profiles button to the main Options screen that opens a profile list with:

• Create
• Rename
• Duplicate
• Reset (with confirmation)
• Delete (with confirmation)
• Open Directory (one click to open the profile folder)

Profile Editor + Target Controls

Click any profile to edit it:

• A persistent footer/toast shows: “Editing profile for: …”

• Change what servers/worlds the profile applies to

• Configure what the profile overrides vs mirrors

• A dedicated Edit Settings… flow that:

  • Temporarily applies the profile
  • Lets you change settings through normal Minecraft options screens
  • Saves differences back into the profile
  • Restores your global settings on exit

Active Profile Indicator

Shows a small, unobtrusive label in the Options screen:

• Active profile: <name>
• Active profile: Global when none is active

This makes it obvious when it’s working.

Mod Menu Compatible

• If Mod Menu is installed, Professional Profiles appears like other mods and opens the same UI
• If not, everything still works via the Options button

Compatibility

• Client-side only (no server installation required)
• Allows Resource Packs to be added to Profiles
• Fabric for Minecraft 1.21.11
• Works alongside common client stacks (Sodium/Iris/etc.) because it only manages client settings

Notes / Limitations

• This mod focuses on options.txt (vanilla settings + most keybind entries)
• Mods that store settings in separate config files won’t automatically be profiled
• When editing a targeted world/server's profile while in the targeted world/server, you will need to rejoin to apply changes.
