Warcraft 3 mapping tool: Widgetizer - obsolete
The widgetizer was a very powerfull tool. Using it mainly increasing the preformance (fps) and reduces the loading time.
You can download it here.
Some time ago most mapmakers suggested that maps should be widgetized & optimised before any public releases.
Today mapmakers only use the Wc3 mapoptimiser in version 4.8 or higher from here.
The mapoptimiser in higher versions includes what this old widgetizer did.
