I think this is what you are looking for:
Just don't use Class Globals definitions in your Class, compile It to a library, in a New project check your library in the libraries list, dim the class, and you can use its methods without need to initialize the Class.
Tip I use:
I created lots of libraries and custom views, so to find them quickly, the ones I use in all my projects I name them beggining with a ! so they appear att the top of the list. Example: "!MyFunctions".
