i'd like to know where the real difference between zclasses and just a bunch of objects and propertys. What is an object more than just a bunch of variables and functions?

but (for small collections) isn't it possible to use folder + properties + objects instead of classes ?

what are the real problems i'm likely to encounter doing so ? scalability ? speed ? maintenance ? ZClasses give you inheritance. They go into the "Add List" and, therefore, are easier to instantiate. They hide irrelevant details.
