[GNC] Post crash recovery log file suggestion

[David G. Pickett]

As 4.9 does abort ungracefully from time to time, I grow weary of reentering my unsaved transactions.  I suggest that you post them to a new sort of log file as I go, so I do not have to save megabytes of almost duplicate files so often to avoid this.  Of course, if I leave the cursor on a modified line, I still might lose that line, unless you can log that along with its state when I change tabs.   (Maybe I should be warned when I change tabs that I left an uncommitted transaction, not later when I save?)  When the app starts, it can check the file and replay.  When there is a save and the normal files are closed or flushed to disk, the new log file can be truncated.  It'd be very much like an RDBMS log.  And perhaps a way to allow us to save less often?
