Paulo,
I'm new in the MMortal community since a few days and was wandering about the same subject. After reading this thread, my conclusion is:

If I want to make 100% flexible CompanyClassLayer (CCL), I have to subclass every library in te mmortals\common30\libs folder in its own folder.

If I do so:
- I might get problems with MMortal updates ..?
- I can't use the qstart utility beacause it initiates the AClasses from the Cclasses, skipping my CCL classes.

The advantage of such a CCL is you can make your own framework upon the MMortal framwork.

Do you think my conclusion make sence ? or is there an other way to change the framwork.

Thanks
Jan Peter
