Memory is every doc in the directory in one table. It is the answer to "what do we actually have?"
Filtering
The filter menu narrows by:
Two extra filters are worth knowing: unindexed (docs not reachable from the nav) and plain (documents with no interface).
Ordering
Ordering is the only display control — there is deliberately no grouping or column picking, because directories reach tens of thousands of docs and the table renders incrementally to stay usable at that size.
The details panel
Selecting a row opens its properties without leaving the table.
Acting on docs
From a row you can move a doc, open its settings, or delete it.
Reorganising
Reorganise directory re-files the whole directory in one pass — useful after a long stretch of work with automatic organisation turned off.
Switching directories
The strip along the top switches directories without leaving the page.
