GMail Hilite is a Chrome extension designed to improve Gmail inbox management by allowing users to highlight email rows based on customizable rules. This tool enables users to quickly identify important emails through visual cues, such as colors assigned to starred status, unread state, labels, and sender information. The intuitive interface allows for easy configuration with a priority list of rules that can be adjusted simply by dragging them.

With features like background and text color customization, the extension caters to various preferences, including dark mode compatibility. GMail Hilite emphasizes user privacy by only accessing necessary data for highlighting purposes and not reading email content. Being open source, it allows users to view, report issues, or contribute to its development, ensuring transparency and community involvement.
