From "About Classic Menu":

> ## Classic Menu 2.8.1
>
> by Sig Software
>
> ## Introduction
>
> Classic Menu brings the classic Mac OS apple menu back to Mac OS X,
> replacing the system's built-in apple menu (but keeping it within
> easy reach). It also lets you customize the ordering of the menu
> items and include separators.
>
> ## Requirements
>
> ? An Apple Macintosh or other MacOS-compatible.
>  ? Mac OS X 10.4 or later.
>
> ## License
>
> Classic Menu is freely distributed as trial software. You are
> permitted to evaluate it before discarding it, or purchasing a
> license. The unlicensed version is fully functional but occasionally
> displays a reminder to purchase a license.
>
> Classic Menu costs just $10 per license. Licenses can be purchased
> online at Sig Software's online ordering page:
> <http://order.kagi.com/?BX>
>
> ## Getting Started
>
> When Classic Menu is launched, the appearance of the apple menu icon
> will change. The system's apple menu can be accessed by control-
> clicking the apple icon. You can change how to access the system
> menu in the preferences.
>
> The new apple menu lists the contents of the Classic Menu Items
> folder in the Preferences folder of your user's Library folder,
> which is created containing a few initial items. Items can be added
> to this folder by dragging files from the Finder onto the apple icon
> or using the commands explained below. They are displayed in
> alphabetical order by default but can be reordered (see below).
>
> To open a file or folder, select it from the hierarchical apple
> menu.
>
> To reveal an item in the Finder, select it while holding down the
> Command key.
>
> To show the information window for an item in the Finder, select it
> while holding down the Shift key.
>
> ## Ordering and Separators
>
> New in version 2.8, Classic Menu lets you customize the ordering of
> the items in the apple menu, and add separators. This works by using
> prefixes on the file and folder names inside the Classic Menu Items
> folder.
>
> Each prefix is followed by a >> (double right angle bracket).
> Classic Menu sorts the items according to the prefix, and any items
> with the same prefix are ordered alphabetically. This enables you to
> group items and control the ordering precisely.
>
> You can also include a separator in the menu by creating an empty
> folder in Classic Menu Items whose name is the appropriate prefix
> followed by a single hyphen (-).
>
> Here is an example of how to name the items in the Classic Menu
> Items folder to create groups:
>
> A>>Documents
>  B>>-
>  B>>Accounts
>  B>>Invoices
>  B>>Legal
>  C>>-
>  C>>Applications
>  C>>Office Apps
>  C>>Utilities
>
> Here is another example using numerical prefixes to set the ordering
> exactly:
>
> 01>>Documents
>  02>>-
>  03>>Legal
>  04>>Accounts
>  05>>Invoices
>  06>>-
>  07>>Office Apps
>  08>>Applications
>  09>>Utilities
>
> For numerical prefixes, make sure you always use the same number of
> digits, padding with zeroes if necessary.
>
> ## Other Menu Items
>
> In the Classic Menu, the Menu Folder submenu contains:
>
> ? Add Alias? lets you select an file or folder to be added to the
> menu.
>  ? Open in Finder opens the Classic Menu Items folder in the Finder.
>  ? Select New? lets you change the folder whose items are listed in
> the Classic Menu, instead of Classic Menu Items.
>
> The Classic Menu submenu contains:
>
> ? About? displays version information.
>  ? Preferences? accesses program settings.
>  ? Register? displays usage and allows purchase of a license code.
>  ? Quit stops Classic Menu running and returns your apple menu to
> normal.
>
> Tip: to share apple menu items between the Classic environment and
> the rest of OS X, choose Select New? from the Menu Folder submenu,
> then select the Apple Menu Items folder inside the System Folder
> used for your Classic environment.

Unfortunately Classic Menu is no longer being actively developed.

The menu items can also be grouped and ordered, together with
separators.

The standard OS X apple menu remains accessible, either by clicking in
a user-specified area of the apple icon or holding down a customizable
modifier key.
