The current Windows version was designed from the ground up as a multithreaded program to give the user full performance plus full control over the programs functions. The user has full control and the ability to edit all the toolbars, menus, and file type actions to control most aspects of the program.

The program is well regarded by reviewers and end users alike and currently retails for AUS$85 (about US$57).
