Shiny Droplets are a bundle of small applications that integrate with the finder toolbar, providing a fast shortcut to your favourite text editor.
Features:

• Files dropped onto a droplet will open altogether in the same editor window (provided the editor supports that).
• Selecting files and then clicking a droplet will make each file open in its own editor window.
• Finder integrations (look and feel and items selection)
• Shiny Droplets are free and open source!
