DESCRIPTIONS FOR DECKS: Have a place to write feedback as you put your deck through iterations.

You could write things down like:
• Maybe remove this card
• Maybe add more of this card
• Lands feedback
• Reminders of how to play the deck properly for when you haven't used it in ages.
• Wishlist of cards to get when you have more wild cards.
• How successful this deck was in ranked.
• Reasoning behind your side board

There's so much unused space on the Deck details area of the desktop app and I think this area could be easily added.

Please consider my feedback - I'm currently using notes and spreadsheets but I'd like a built in solution.
