I just bought the Calibre Companion for my Kindle Fire and have set it up with my content server.

Then I realized there is a major flaw in the structure for me ... unless I am missing something.

I can only use the Calibre app if I am connected to the Content Server, right? In other words, it doesn't seem possible to use it "offline". If I am missing something, please let me know.

The issue: my content server is on my PC. This is a work computer (professional and personal). When I am working on the PC, my Fire is off and elsewhere.

When I'm using the Fire, for reading or whatever, I am not at the PC, and it is turned off. I do not want to leave the PC on 24hrs/day just so I can use Calibre on the Fire...to say nothing of the fact that it wouldn't help when I'm using the Fire away from home.

It seems to me there are 2 potential solutions: 1. having some way to store my Calibre content in the cloud. I suspect this would require more resources than the Calibre community has.

Second, create a way to download the catalogue only (authors, titles, metadata) to the Fire. Ideally, it would indicate if a book is stored locally or not (just as Amazon distinguishes between books in the cloud and books on the device).

I now have so many ebooks that Amazon's display options, including its pitiful collections, are very limited. I had hoped that Calibre on the Fire would give me the display flexibility, especially for series, genres that the desktop version offers.

But if I can't use the Companion offline, it's useless.

I don't mind having spent the money. I've gotten quite a lot of value from the desktop version. I'm simply disappointed that it's not going to work for me on the Fire ... unless there is an option I have missed.
