nil has been added.

set-of or union constructors. For more details, see OKBC 2.0

operation has been tested with Ontolingua server.

over the network.

different types of mouse-clicks have been changed.

all (appropriate defaults are provided).

case-sensitive, rather than all coerced to uppercase.

predicate (so far, can only use predicates we supply).

can't think of right now.
- Hierarchy graphs are drawn more compactly now.
