Support .djvu extension files

Many textbooks exist online only in .djuv forms.

It would be all to the good if marginnote could support .djuv files.

Thank you for writing in. I have already raised your request to our Development team. As mentioned earlier, all user requests will be considered and implemented but we cannot assure a time frame when it will be put into effect. Please feel free to contact us again if you need any assistance and we will be happy to provide further help.
