It may have been the move to journaling...

It should have worked. As a test, I just put a backup from 4.3 on my Touch. It was migrated with no problem. The change in the journal mode shouldn't is unlikely to cause a direct problem. It changes how the database is opened from then on. But, it's a bit hard to test and prove.

Kobo Utilities offers a good surface explanation of what a function does, even to a newb like me, but I wish there was a warning dialogue for potential consequences of some actions.

I may have clicked "Refresh the list of books on the device", or "Update metadata in device library". These sound pretty innocuous, but I really have no idea of negative consequences by clicking those. Now that I manage everything in Calibre, there's less fear of a SNAFU.

The first of those is simply to reread the device and get the book list again. The latter is to update the metadata on the device from the calibre library. The latter can cause a problem but only if the metadata is wrong. Or you use the options to change the reading status when you don't really want to.

These days I simply avoid everything in Kobo Utilities except to backup the database. Maybe one day I'll find the Wiki...

Well, you could try the help in the top right corner of each dialog.
