Hei,
I am a new user who has just entered his first 1000 cards into the inventory. I find the deckbox-interface to be very smooth and effective to use - great work! The following small enhancements I'd still find useful:

Adding a card to inventory: selecting language: new option "Asian"
- I am not able to tell a difference between one Asian language from another. It would be useful to have a generic language "Asian" to indicate that it is some of the Asian languages. Currently I am erroneously marking them all as Japanese.

Adding a card to inventory: selecting language: new option "European"
- As above for "Asian" languages, but a generic term for European (non-English) languages one could use when not knowing what language the card exactly is.

Adding a card to inventory: selecting additional characteristics: new option "black bordered" (or foreign black bordered, "FBB")
- I have some cards from foreign sets, for example from some Asian Chronicles set, in which the cards have been printed with black borders (unlike in the original English set). It would add value to be able to indicate this is some standard way.

Thank you for the nice site!
Antti
