Importing/exporting from/to CSV and other formats would be desirable.

The idea is to scan lots of bar codes first and store their information on disk, then enter a "bulk identify" mode where informatin for each bar code is fetched and the user can identify the item.

i.e. alphabetically by title/artist, chronologically, etc.

Right now, images for each item are pulled from the internet, but for many items no image is available. It'd be great if you could use the phone's camera to snap cover images yourself.

For that to happen, the images need to be stored persistently on the phone, though. That's not happening currently, because storage on mobile phone is limited! But it would be a good idea to add the option of persistently storing cover images on the SD card. Adding your own pictures would then be a breeze.

I'd like to synchronize my collections between multiple devices. If I make changes on one device, I want those changes to show up on my other devices as well.

Use the Barcode Scanning Apps in the Market instead of having the code built into you app. That way people can choice there favorite scanner. And you don't need to worry about updating the scanner code. And you app would take up less space.

I haven't been able to find a collection manager that can store my data stored in the cloud. I'd prefer Google Docs storage but a self-hosted mysql/postgresql database would be fine. Perhaps the persistence layer could be implemented as plugins so people could write their own.

It would be nice to build a database so that we can work together to improve the data. I can get info on barcode and title but often the rest of the info is missing a shared effort might help us all.

Have a Display Mode that Just Shows The Images of the items sitting on shelves. I would like it to be drag and drop so people can tinker with ways to sort there collections. A Slideshow mode might be a nice screen saver too.

I'd like to add a rating of one to five stars to each item in my collection, and then be able to sort items by their rating.

Link items to local or online retailers, of just to the ShopSavvy app.

When scanning in books you get a few regular results, and massive numbers of results from ebay, add an option to ignore those when pulling search results

Taken from "Who did I lend this book too?":

Same idea, slightly tweaked. I expect this is already catered for: I have multiple (real) shelves, boxes in storage, school/office. Would be great to be able to name/photograph a location where the item is, so I can locate the item really quickly.

would you be able to use existing packrat users data to a database to increase success rates when scanning barcodes... i have found that scanning my vinyl collection left me with almost 0% success rate... have spent a long time searching artwork and inputting data.. it would be nice to think it could help other users

PackRat on Android phones is great, but what about the iPhone/iPod Touch? It'd be awesome if this app existed on those phones as well.
