Stop Sign Documentation
Two people in one entry. Somebody gets asked before they save.
Installation
Two commands, no configuration, and what changes on your site the moment it is installed.
How it works
What Craft already does, why Stop Sign keeps its own presence table, and the one method the save guard wraps.
Usage
What each warning means, what the save guard asks, the utility screen, and the Twig and console interfaces.
Configuration
Every setting, what it defaults to, and the three that are worth thinking about rather than accepting.
Locking
Why locking is off by default, the three rules that keep a soft lock from becoming a support call, and how to get unstuck.
Troubleshooting
Nothing appears, everybody is locked out, the banner flickers, and the other three things that actually go wrong.
FAQ
Cost, what it stores, why it does not use Craft's activity table, Snitch, Locked Entries, performance, and what happens when you remove it.
