## Description

SiteDelta Highlight is a powerful Chrome extension that helps you easily identify changes made to any website since your last visit. By adding a simple Delta icon to your browser toolbar, it allows you to highlight all altered text content on the current page with a single click. You can cycle through changes and even define specific scan or ignore regions for tailored tracking.

Advanced configuration options enable automatic highlighting of changes on known pages every time you visit, as well as periodic checks for updates. For change notifications without opening pages, you can use the complementary SiteDelta Watch extension. SiteDelta Highlight is an essential tool for users who want to stay up-to-date with content changes effortlessly.
