This could work both ways, first is a way to create backups of the current collection and also will be able to manage collections from other people (we have different collections but pull them on when we create decks) and thus know who owns what

Report for the owned cards with their prices and total price of the collection

MTG Studio do be changed to be able to self update whenever a new version is available and also to update its configuration file and reuse old collection files.

It appears that you manually have to note the used quantity of cards in your collection. When you pull a card into a deck, it would be nice to show that it is used. I realize that some people create a variety of phantom decks. But used is a separate column and the card would still show in the collection.

While perhaps difficult to implement, having offline deck testing capabilitiy - perhaps by allowing the user to play a deck idea against a computer opponent using a pre-built (with possible options for tournament-winning decks, particular color/theme decks, etc.) - before actually trying to play the deck live would be a phenomenal feature in my opinion.

You already have the option which cards are missing from a predefined deck, but what we would really love it the possibility to see which decks can be built with the cards we currently have. So that is auto-checks which decks are only missing very few cards.
I know this might be processor intensive, but my... that would be one of the best features you have ever done.
Keep it up.

Collection to be exportable/imprtable to/from zip. A feature of creation of automatic backup zipped copies is planned for the future. It will have the setting of how often to perform the backup

Display the expansion symbol before the set abbreviation

Add the ability to set the buy at or sell at column to a store price or % of the store price.

Be able to update 1 field in all selected cards. For instance, set condition = mint for all selected cards. Very interesting for some columns

Have button which allows to switch between front and back of the Duel Face cards.

Build a web site with the same functionality like MTG Studio which is
- cross-browser
- cross-platform
- allows you to maintenain your collection/decks from anywhere
- zero installation
- no Flash, Silverlight, etc.
- subscription bases. Something like $1 per month, $10 per year..

Thumbs View. Ability to display the cards with images instead as grid rows as in MTG Online.

Save the window size from last launch

Add "Batch Update" command which allows you to update a whole set, or all filtered cards, or all selected cards from either card pool or deck to the collection. The dialog will default the possible editable column values and allow changing the default values.

Enhance the starting hand features with the ability to draw additional cards, take a mulligan, and deal again

Ability to "Print Proxies"(tournament illegal paper versions of the cards in your deck).

Work on Options dialog allowing you to select the way the default price is calculated.
- be able to pick favorite store
- be able to pick AVERAGE, MIN, MAX price
- be able to pick a weighted price depending on store availability
- be able to add a Modifier index to the prices. For example Store Price - 20%.

make a companion ipod ap to export collection...so no matter where you go you have your collection with you...this would make your offerings complete

Enable prices to update to include the quantity field as well as correct prices for foil cards.

So example: Say you have 26 Tear Drop Kami's in your collection. The price field should say 5.98 instead of 0.23. 26x0.23, in other words.

Also, prices for foil cards are listed to be the same as non-foil. This is incorrect. All foil cards, common-rare, have different prices then their non-foil counterparts.

thanks.
