Splinterlands game evolved so much and brought new features, improvements and some great changes in the User Interface. But there are still some things that are in a specific way for so long, which could really enhance the usability and make the game more active.
Such a feature that could be improvement is the "Cards options" list-box in the CARDS view. While it could be good in the low levels accounts, in high level ones is just one extra actions needed each time to see your cards clearly. Instead of having the current default value to PLAYABLE I would propose it to have it to OWNED. Filtering is quite important in the dynamic of the game and having it set this way will sure speed up activity and actions within the game.
Work smarter not harder and with the new default for sure will make things easier.
Please consider this as it is a 1 minute update which will bring great value!
