Greetings!
First of all thanks for the great software, keep up the good work!
I have a PocketBook 302 reader and use calibre to organize and sync my books to the device. The reader gets recognized as Pocketbook 360 not as Pocketbook 302, which isn't a big deal, especially considering the 302 is quite new model.
But what matters is that the supported files are not properly described in calibre: neither for the 302, nor for the 360 model. For example both devices support zipped FB2, but calibre does not allow such archived files on the device and suggests conversion. And whilst those files can be converted to say EPUB without issues, there's really no need to go through this extra step. The devices support zipped FP2 and generally zipped ebooks without any issues.
So if you could pretty please update the supported formats for PocketBook 302 and Pocketbook 360 in a future release
Here are the actual supported formats (they're almost the same for both readers):
PocketBook 302: Fb2, FB2.zip, TXT, PDF (DRM), RTF, HTML, PRC, CHM, DJVU, DOC, EPUB (DRM), TCR, ZIP
PocketBook 360: FB2, FB2.zip, TXT, PDF (DRM), RTF, HTML, КНР, CHM, DjVu, DOC, EPUB (DRM), TCR, ZIP
Thanks in advance!
