Can you rearrange the (user added) menubar icons properly in Snow Leopard?
Only Apples and certain third parties.
I explained this in such good detail elsewhere. I wish I could remember where it was.
Basically, Apple's and certain third parties like iSlayer, utilize a certain app called "SystemUIServer" which is a special app container that sits in the menubar to the left of the Spotlight menu and houses any "Menulings" you launch. Those menus such as Battery, Airport, Time Machine, Volume, etc are special in that they simply inject themselves into SystemUIServer and SystemUIServer gains control over how to display them allowing the user to move them and remove them like you can icons in the Dock. In other words, SystemUIServer acts like a Dock for your menubar. But only specially coded apps can go up in it. Others have to "hack" themselves into the menubar.
But unfortunately Apple never opened this feature up to third parties, and only ones who cracked the code know how to put their utilities up there. And even then, only certain self-contained apps can actally go in there. Big apps like DragThing and WeatherPop are too big to be contained inside SystemUIServer, since adding an icon to SystemUIServer launches it and removing it quits it, you can't have that same simple control over things like DragThing etc.
Apps like PTHPasteBoard though allow simple control over where the app goes, but only from a choice of three places. Far right which places it to the right of SystemUIServer. Far Left which places it leftmost. And Middle, which places it directly to the left of SystemUIServer depending on the launch order.
So to answer the question, no. It does not, because only certain apps work that way. Other apps that place themselves in a menubar simply do not have the ability to do it. And sadly that is how it will always be until the app creator creates a separate app to sit in the menubar while the main app runs iconless in the background.
