I must have changed something, because I no longer have access to "send to device". I have "save to disk", and the metadata and configurations for my devices. THey are recognized in Calibre, but the "save to device" function has disappeared, even AFTER I made sure it was on the toolbar.
I have no idea how to "save to disk", so unless I figure out this save to device problem, I can't get new books on it....
I bet this has to do with my resetting to defaults. I did that as an attempt to speed up Calibre. Didn't speed anything up, but now my whole library looks and acts weird.
