In case you don't have the required expansion, Nexus doesn't tell you the name of expansion in which the preset name can be found. I have a made a Python script (2 days work) to find the expansion in which a preset is. Usage is pretty easy and in spite of hard work by myself, nothing except the bare functionality works. Install the dependencies first.

Code:

python -m pip install --upgrade BeautifulSoup4 colorama

To use it:

Code:

python nxp.py "<PRESET_NAME_HERE>"

Don't ever forget the quotes (" ") around the preset name.
You will get nice colored output
If you try to figure out more options, it won't just work for reasons unknown.

How is it done?
Look in the script, plzz. I have attached zip which contains code and a generated JSON which stores all required data. If you delete it, you need to run with the -u option which will scrape off data from ReFX.com

Hope you like it.
