Multiuser editing alert

This module enhances collaboration in the Silverstripe CMS by providing real-time alerts when multiple content authors are editing the same page. It helps prevent accidental overwrites and content conflicts, making team-based content management smoother and more efficient.

Key Features

• Visual Page Indicators — Blue dots appear next to pages in the site tree to show where authors are currently editing.
• Multi-User Warnings — Red dots and large warning messages appear when multiple users edit the same page simultaneously.
• Smart Polling — Polls the server every 3 seconds during multi-user edits and reduces to ~24 seconds for single users to save server resources.
• Automatic Cleanup — Users are automatically removed from the editor list when they log out or close their tab.
• Configurable Timing — Polling intervals can be adjusted via configuration to handle high traffic scenarios.
• Lightweight Assets — Uses tiny SVG files for dots and icons to minimize download size.

Philosophy

The module is designed to be unobtrusive yet effective, providing essential collaboration alerts without overloading the CMS interface or server resources.
