the first days, while I was playing with poterm, I had 'unfortunately' deleted /mnt/ext1/system
so I did a firmware upgrade and all gone ok.
now I was playing with extensions.cfg to test some app and a question arose:
why in extensions.cfg there are ICON_PDF, ICON_EPUB and so on if I have always the same icon for any book regardless of the type (epub, txt, docx, djvu....) ?
may be I didn't restore such icons?
in this case where can I find them and where should I put them?
