Given that OF currently displays all matches in Project View, and (following a date-range search) will place the selection highlight on the relevant parental/ancestral action group of any task that is inheriting an effective due date, does the gap feel like a practical obstacle ?

If it does, one solution might be to re-work Where in OF so that, while the Applescript library lacks an effective due date property, Where In OF directly queries the cache for that information.

(i.e. adding a preprocessor that converts the existing AS-type queries to SQL queries, and allows for the addition of some custom properties)

(possibly verging on the baroque again here :-)
