UI suggestions

I would like a few additions to XMage if it's possible.

**Deck Editor**

I find it helpful to have an additional window where I can put cards that I would like to keep in mind to add to the deck while I am testing the deck with different card options. Therefore I thought maybe you could could cut the Sideboard part in half to have the upper part of it to be the Sideboard and the lower part something called like a Maybeboard.

**Card Viewer**

Do you plan on a search function (colors, types, etc.) there or do think people are supposed to use the Deck Editor for this?

I would like to hear your thoughts. Thanks in advance.
