Missing Your Mac Os9 Functionality? WindowShade X Roll window up

[jedipi 0]

are you missing your classic Mac OS functionality?
I do want to have the windowshade function for every
window in my OS X system. The windowshade functionality
that's been in the Mac OS since System 7.5 .
Double-click a window's title bar, the window "rolls up" into the title bar.

I found a great software from Google search.

WindowShade X --
With WindowShade X, you get everything Mac OS 9 could do and more.
WindowShade X has for methods, the minimize button, double-clicking
the title bar, Control-double-clicking the title bar, and pressing
Command-M, to roll up into the title bar.
It also can make the window transparent, minimize a window to the
Dock or hide the application.

WindowShade X is US$10 shareware, and it's a 2.11MB download.

Give it a try.
