I’d like to suggest two new features for the next firmware update:
Author and title metadata for .pdf, .mobi and .epub file formats are readable by Boox but .docx and .djvu are not. Please make metadata readable for .docx and .djvu file formats, too. Many ebooks, especially old ones, are available in those formats. Converting .docx to .pdf prevents you from writing on them while converting .djvu files to .pdf is not really an option since the created .pdf files can be 5 to 10 times bigger in size.
Non-system apps like Evernote, Pocket and Google News show texts in bold. For some fonts, the produced text in bold is very hard to read. Please make this feature able to be deselected.
Please, if possible, add a device activation password or drawing pattern like in tablets and mobiles.
