Guys i created a new mod manager for l4d2 and any game that supports steam workshop
Controls:shift + left click to select multiple vpk files and u have to find the addon path it doesnt do it for you AND u have to manually save the loadout here are two reasons why i cant upload it on the steam workshop or the steam frontpage

🔒 1. Steam Workshop Only Accepts Game Content — Not External Tools
The Steam Workshop is designed for:

Maps

Skins

Models

Sounds

Scripts (within the game)

ModPilot is a standalone external tool — not a mod for L4D2, but a mod manager, so it doesn’t meet the Workshop requirements. Valve restricts uploads to actual game content, not software utilities.

🛑 2. Steam Storefront Requires a Full Steam App Submission
To appear on the Steam Frontpage or Store, you’d need to:

Pay the Steam Direct fee ($100 USD per app)

Package your tool as a complete app with installer

Go through legal, financial, and review processes

Build full branding (store page, trailer, support plan, etc.)

This process is designed for commercial games/apps, not lightweight community utilities.
