Feature requests: shuffle hand action, remove most recent counter action, better separating of attackers/blockers, better shuffling cards to bottom

• 1. Add 'shuffle hand' action
  It's very easy to spot which exactly card was played from an opponent's hand, which forces players to constantly shuffle their hands in competitive games. A semi-automated action would at least make it more convenient.

• 2. Add 'remove most recent counter' action
  Currently the only way to remove some counters is to drag them away, which is very time-consuming when you have a lot of cards to remove counters from. Such an action would be very helpful in this case.

• 3. Optimize the way attackers and blockers are separated.
  Attacking and blocking should be a group action, where separating the cards would only happen at the end of it. Right now when you attack/block with multiple creatures at once, it takes some time because separating attackers/blockers happens after every single creature's attack/block.

• 4. Improve the way cards are shuffled to the bottom of the library
  All cards should first be sent to the bottom of the library, and then shuffled. Currently they are simply put to the bottom in a random order, so players can see to some extent in what order they leave the table.
