The 1.0 version of QDisplay for Mac was provided as a free download on our website. This free Mac application was originally produced by Figure 53, LLC.
From the developer:
QDisplay is a very simple information window for OS X, built to use with QLab. It does only one thing: display a floating window in which you can specify a message using AppleScript. AppleScript language is a set of lexical conventions, syntax, keywords, and other elements.
