phpMyAdmin Designer Auto Arrange

About

phpMyAdmin Designer Auto Arrange helps developers who use phpMyAdmin’s Database Designer on a local server (http://localhost/phpmyadmin/… or http://127.0.0.1/phpmyadmin/…).

What it does

- Adds a floating Auto Arrange button on the Designer canvas.
- Optionally arranges tables automatically when you open the Designer (toggle in the extension popup).
- Uses foreign key relationships from phpMyAdmin’s own config to place highly connected tables (“hubs”) closer to the center, and more isolated tables toward the outside.
- Uses real pixel width and height of each table box to avoid overlaps, with extra horizontal spacing when the window is wide.
- Keyboard shortcut: Alt+Shift+A to arrange the current tab.

What it does not do

- It does not send your database schema or any data to external servers.
- It does not modify MySQL: it only changes on-screen positions in the Designer (remember to use phpMyAdmin Save page if you want to keep the layout).

Permissions (why we need them)

- localhost / 127.0.0.1 phpMyAdmin URLs — so the extension can run only where you use the Designer.
- storage — saves your popup preference (e.g. auto-arrange on load).
- activeTab — used when triggering arrange from the extension UI in the active tab.
