Publish Prefixes lets you tame large/unweildy publish and edit menus by grouping channels by using prefixes in your channel names.
Say for example you had multiple 'Product' channels... you can group them all under a single parent 'Product' menu item by prefixing the channel names with 'Products: '
If your channel names were:
Clocks
Widgets
Tools
You'd rename them to
Products: Clocks
Products: Widgets
Products: Tools
This would create a Parent menu item called Products, with Clocks, Widgets and Tools as the child items.
Simple.
