I built a free GPL viewer for Microsoft NPS/IAS RADIUS logs

I spend enough time looking at raw Microsoft NPS/IAS logs that I made a small viewer for them:

https://github.com/eenest/nps-logview

It is portable, no installer, and currently has Windows x64/x86 plus Linux builds.

It decodes common RADIUS fields, request/reply pairs, Access-Rejects, Microsoft/Cisco/Juniper/Fortinet/Avaya/Meraki/Palo Alto vendor-specific attributes, and can export decoded logs.

This is not a paid product. It is free/GPL. Tips are optional, but not required.

I would appreciate feedback from people who troubleshoot NPS, Wi-Fi 802.1X, VPN, or RADIUS issues. I am especially interested in real-world parsing problems, missing attributes, or confusing UI behavior.
