Thanks,

'Natural order' (un-sorted), original{id} order closesly follows the Date column if you do not change that value.

I noted original{id} because I believe there are events that impose a new ID number

Having to burden the database with a custom column to get at something that exists naturally tends to 'off' my sensibilities .

By default, Calibre starts with the last sorted column
OR
using the tweak: ID: sort_columns_at_startup
'None' being the standard behavior (above)

sort_columns_at_startup = [('id',0)]

works on Windows for the initial startup of a Calibre session
