Some notes about the tools:
PolyBoost will work in 3ds max versions 5 - 9, 2008 and 2009. Most of the tools work on all subobjectlevels, so it's one tool for all modes. UVW-mapping is kept
intact for all the modeling tools and work with modifiers in the stack. Many tools
have an optional functionality when the shift key is pressed. This will either apply
the tool on the current selection only, or do another variation of the tool. Shortcuts
are available for all tools that do not require an interface in order to be useful. The
PolyBoost main interface, where all tools can be found is always available by
shortcut key or from a quadmenu.
