The main improvement in version 1.0.1 is “auto refresh”. As you edit the text files in your Website Folder, the app watches for changes. When an update is detected, a web socket is used to send a notification to the browser that causes a refresh.
It feels like freedom to work on a site in a text editor and see the browser update as soon as you press ⌘S. Flipping back and forth to refresh is a thing of the past!
The new version also supports drag & drop to get a site going. You can drag a folder onto the Dock icon or Website Folder section of the window.
