Hi Deckstats.
First of all, many thanks for creating and maintaining this service, it currently is my one place to store my ever increasing collection. Your import / export functions makes it easy to use tools like DelverLens together with deckstats.
For analytical and collection purposes though, there is one feature in particular I am missing, to see when (Date / time) a card entered my collection.
This information would help in understanding when and where I might have put a physical card, and can be used as a gauge to see when my collection is building the fastest.
This feature could simply be one of the columns to turn on / off.
Other simple things could be ability to filter on your collection page. I.e. filter on set. Currently there is only the option to search for card.
The items you capture during import / export are to me, and I am sure others aswell, extremely important - like condition, language etc. And as a comment, most other online collection sites don't capture these detail - so kudos!
Also, the deck tutor is a lot of fun.
Again, thank you for the service.
Best,
Karl
