@dlandon I think I've discovered a bug with the plugin. I'll give details below. Let me know if I should report it on GitHub and I will.
I am running UD 2019.06.18 and unRAID 6.7.0.
Steps:
Mount a partition in the drive, but change the name of the mount (by clicking on the name, changing it, and pressing enter)
Create a script for the mounted partition or drive
Save the script
Edit the script (which now appears as a code icon)
Make some change and save it
Observe that the entire configuration appears to be wiped out, and is gone from the \flash\config\plugins\unassigned.devices\unassigned.devices.cfg file as well.
Let me know if you need more details to reproduce this.
EDIT: It looks like it's even simpler to reproduce than I initially thought. I am updating the steps. You do not need to make the script on the mounted partition. Editing a script that corresponds with any renamed partition is apparently enough to cause this behavior.
