I found sort history in prefs backup, the last one is 'timestamp' (IIRC that's the internal name for 'Date' ). I think I might have temporarily shown and click sorted on Date several weeks/months ago when I 'lost' a newly added book.
I can't imagine why I would want an almost forgotten ad-hoc sort that I did months ago sticking its oar into what I'm doing now - perhaps others would.
If I could, I would toggle column click sorting off, as I've triggered it accidentally a few times when dragging or a resizing a column etc. I can do ad-hoc single column sorts with the Sort by feature in the booklist context menu.
I noticed the sort history in prefs_backup for my _Media library contains custom column names from my _Main library; such as #wordcount and #last_action_date. Those columns have never been my _Media library. Maybe I should remove sort_history from prefs_backup and rebuild the database.
I think the resetting of startup was happening if I did just about anything in View Manager. I noticed it whenever I went into config. I changed it back to Published and exited whilst in Author/Publisher View. When I started calibre, instead of being in the Published view I was in Author/Publisher view, and the Startup VM was set to *Last View used.
After reinstalling 1.3.2, I repeated the above steps, the Publisher view remains locked in as my startup View, irrespective of what view I was in when when I terminated calibre, just as it always has.
Added : Why don't you give Rellwood a nudge and ask him to try the new version, it was his idea to create new views from existing views. If needs be I can hack 1.3.2 and call it Booklist Manager
