Hi
I use Rocket Dock, in my case it's mostly for my software but I have a couple of folder links on it too.
You could use the whole thing for folder links if you wanted to.
It really doesn't have a limit as to how many links you put on it, it's dependent on icon size.
However you have no limit using Classic Shell either, it all depends on what display style you select.
I have it set to open multiple windows for the start menu, so all of my folders are shown at one time in an alphabetized list in multiple side by side collums.
If you wanted your folders to be at the front of the list, you only have to label then 001, 002 etc.
