Edit with full-control. Code helpers, generators and shortcuts including Zen Coding are there when you need them. Out-of-the-box version control and backups give you quick access to revisions without having to configure servers. Preview in the editor (full-screen or split-screen live previews), in another window, on multiple monitors, in multiple browsers and even through external devices (multi-device live preview on smartphones/tablets including iOS, Android, Windows Phone and Blackberry). Save time and catch errors quickly by previewing as you edit HTML5, Markdown, LESS and other file types. Built-in HTML Tidy can point out invalid markup and suggest improvements. Or use industry-standard W3C HTML/CSS Validators with a single click. Displaying color below each HTML/CSS hex/rgb() color, highlighting of matching block, instant viewing of matches as you select, and searches within tags / attributes / classes / styles are some of the many powerful tools included, in addition to optional plugins. Keep multiple projects open at the same time (with color labels in tabs), create virtual folders to logically organize files from multiple sources and access local/network/FTP folders. Or skip all of it and simply open files from local folders.
