Hello!
First thanks for this software.

It's ideal to get my calibe managed books synced to my tablet. I'm going to get the pro-version today.
I've a question - or possibly a feature request:
Although calibre can't display MHTML-Files, it's possible to import such files. I use them to archive webpages (with FF and palemoon using unmht on Linux).
It's very handy to import them to calibre adding metadata so I can search within my calibre-book-library and display them by klicking within the palemoon browser on my notebook.
But - I can't transfer them using CC (and possibly launch the MHTviewer for those files) to have the same feature on my Android-Tablet

So it would be nice to have the filetype MHTML added to the setup list of bookformats to sync these files as well.
Can that be configured or is this "hard coded"
Cheers
Knut
