    along the same lines: i have always been looking for a way to remove
only the regions that are not associated with any (used or unused)
playlist?  it seems like session cleanup will remove all regions not
associated with an active region (i.e. regions that are only in unused
playlists), as well as the currently unused playlists themselves.  what
i am looking for is a way to remove regions that may have been
created/etc, but are currently not used by any playlist, selected/active
or unused.

    this would help in sessions with lots of editing and thus
creation/throwing away of regions, to help lower the region count (which
seems to slow down saves to a few to ~8 seconds, at least on A2,
depending on the number of regions of course).  as i use playlists
extensively for takes and alternate mixes, the ability to throw out
regions that are "orphaned" from any playlist would be great.  i will
file a feature request if this is not already possible in A2or A3.

    note that i have tried the "delete unused" option in the region
list, but again, it seems to remove regions that are associated with
unused playlists.

    finally, how does cleanup deal with a region that is still
referenced in a snapshot, but not in the current session?

    thanks in advance.
