< The S codes for the most part don't actually use the StylePicker - the only one that actually does is S, which could easily be changed to open the MultiPicker on the Styles page.>

True. That's why I only referred to S rather than also listing other 'just as useful' S-codes. My reply focused solely on this specific question from a user:
<<<< (It would be helpful if users who vote No could add explicit examples of what they think they can not do in the mutipicker, I am not aware of anything.) >>>

Changing the shortcut S to open the MultiPicker regardless how easy it may be is senseless. First, it would take a tool, that at the moment is useful and unique, and make it useless and redundant. Second. It is very common during a project to only want to change a Style and there's no need for the MultiPicker window providing everything the program can do. The user only wants to open the StylePicker and select a style and continue with the project.

Typing S in any measure and pressing the <enter> key and the StylePicker opens instantly. Right click on the Mixer or pressing F7 and the MultiPicker opens and defaults to the RealTracks button. This obviously still requires additional steps and selections simply to open the StylePicker.

What's the benefit to all users when the task at hand is to only change styles? There's no benefit making the S code redundant to the existing Right Click method, or F7 shortcut that opens a dialog window rather than the StylePicker and once the MultiPicker has opened, have to further select the Styles button away from the default RealTracks button? It's faster and logical to only do one thing to do one task. S and enter..........

Anyone with any version can prove to themselves the speed advantage, efficiency and logic of using the S code to open the StylePicker is a workflow advantage over using the MultiPicker if the task is to only change Styles. If your project workflow is doing multiple changes, then of course, the MultiPicker is made for those circumstances.

As you noted in your response, the other S codes are also specific task related shortcuts that are very useful tools that should be in every users toolkit. They provide instant access to recently used and favorite styles list and instantly will open a player to audition demos, as well as other useful shortcuts.
