maybe what you need is to right click on the nav pane header, choose navigation options... choose Custom and create groups then add items to the group. I've not done much with this but I presume you can add tables and associated queries, forms and reports to a group. It's been a long time since I had that many objects of a type in a db. I prefer to reuse forms or reports as much as possible and group by type (so that all tables are together, all reports together, etc.)
The more we hear silence, the more we begin to think about our value in this universe.
