Sucks But Works
Windows only
Change the app_id with the game's app_id
Requirements: Python (Download Here) and Steamcmd (Download Here, From ValveSoftware's wiki)
Python libraries:
pip install requests
pip install beautifulsoup4
Unzip Steamcmd and put the script in the same folder, make a mods.txt file and you'd be set. I recommend using something like TabCopy to get all the open tabs in Chromium based browsers Link Or Export Tabs URLs in Firefox based browsers Link
Usage:
Open all the mods you want in your browser.
Copy the urls.
Put them in the mods.txt file.
Open main.py and change app_id = 0 to app_id = {Your game's appid}
Run main.py.
