My 2 cents: I think most *developers* will have a "testing" file.  Everyone I
know who uses finance software does not have a "testing" file; instead, they
have just one file -- the active one.

Don't least-often-used files simply slip silently off the history list if you
have "too many" entries?  You could have a preference setting for how many
are "too many".

You could also have a context-sensitive right-click menu for deleting a
history entry... manually.
