I think it would be helpful to have card types in the deck builder section instead of lands, creatures, and other. I think the 7 types are:
---
Land
Creature
Plainswalker
Artifact
Enchantment
Instant
Sorcery
---
It would help organization a lot!
Another thing: when searching the database using landscape mode (slide show), there is a search bar that always blocks the name and CMC of the card you are viewing. Also sometimes it just goes back to the begining.
Hope this can be fixed and thanks for the awesome app, Piotr.
