Currently, a logic of the event flow in EventIDE is based on conditions attached to events. This is a historical feature of the original program's architecture. Event conditions allows easy management on layers which contains dense links structures with a small number of events. However, the practice proves a real disadvantage of this approach- the conditions get overcomplicated when multiple links converge to a single event.
Accordingly, the conditions snippets (including the default time conditions) are planned to be moved to the links them self. It's a final step in core design, which is planned to be completed in September 2012.
