FAQ
Q: Where are all the script settings?
A: Most of my scripts make use of the Derpi4U library to provide a consistant UI experience. If you have any of those scripts installed, you will find a new “Userscript” tab in the site’s settings page.
Do note that, same with other settings, any changes you make have to be confirmed by clicking the “Save My Settings” button at the bottom of the page.
