Info for when you get your second wind, no pressure...
Have briefly tested today's release with WinXP, TimeZone:London. No testing done using SD card.
Good news:
I no longer have any duplicates in Collections.
Books appear to be stored in the correct Collections.
All thumbnails now seem to 'stick'. Have tried EPUB, PDF and TXT.
All saved file paths correct as per send-to-device save template
Not-so-good news:
Plugboard assigns do not 'stick' for EPUB and PDF, but they do for TXT
