BOOPSI in AOS1.0 ? How did I miss that

?? :-P
BOOPSI was (along with taglists) THE major shift in the 1.3 to 2.0 upgrade, allowing for stuff like custom-gadgets done in a somewhat
sane way, and later on datatypes.
But I must admit that looking back, useing it for GUIs embeeded into the app pretty much seems like a design-error.
Another "feature" that makes securing AmigaOS with MP and suchlike impossible.
