The 1.4.2 version of Simple Divider for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. This free Mac application was originally produced by One Little Designer. The software lies within Developer Tools, more precisely Webmaster Tools.
From the developer:
Simple Divider is an application that allows you to drag and drop simple separator lines on any Stacks page. You can switch between two theme styles that provide the basic functions used in creating divider tags. The file comes with snippet files you can install in place of the stack, so you can take advantage of the stack's simple use without taking up space in your Stacks section.
