How to store and load global settings

I would like my plugin to be able to store and read global settings (e.g color theme, user preferences).
Does VSTGUI happen to provide support for this?
On Windows I use the registry but it would be nice if there was some other (cross platform) way.

there’s nothing like this in VSTGUI for plug-ins.


Thanks for the answer, sorry to hear that.
How do other developers usually store their global settings on Windows and OSX?
