Topic: Card/Collection enhancements
I have been loving DeckBox since joining a few weeks ago and I have a few suggestions that may make it even better.
1. Show a graph of the price of each card over time on the card details page. It currently shows the current prices and from TCGPlayer which is nice, but I would also be interested in seeing the change over time. There are a lot other sites that have this type of thing so it is probably relatively simple with the TCG API.
2. Value of a collection over time. Since DeckBox is great for managing entire collections it would be really cool to see how the value of my collection is changing. This may be a little complicated since it would require a lot of resources to generate the graph on the fly or to store values for each collection on a periodic basis. Might be more trouble than it is worth, but I think it would be pretty cool.
