That's interesting. A favorites second program menu, with only the pick of the crop.
Yeah, just like a tv remote fav button.
I guess one would have to make a folder on hard drive first, and name it say, Common Programs.
Copy over program shortcuts from original installed locations,
or copy the select ones from the all programs menu,
of Classic Start Menu.
Good to look at the Classic Start Menu help file first, to get familiar.
Go to Customize Start Menu tab, double click on the custom command at bottom right.
Drag the Custom item on left to any location below COLUMN_BREAK.
Double click the custom item, and put the link to the newly made Common Programs folder location on your drive.
The pro users may have easier ways than this.
