For starters, I just want to say that I love this site and use it religiously to manage my decks.
I just have a few comments on the recent UI tweaks:
1. Not being able to directly edit the inventory table cell is bothersome. The contextual dialog pop-up feels like overdesign and now requires a couple of extra clicks to edit a single number. Simple is better.
2. The increased table row height extends the length of the page, requiring more scrolling. While this may have been done to enhance white space and readability, I like being able to see more cards at a time without having to scroll. I tend to build a lot of singleton/commander decks so my deck tables will be longer anyway. The increased table row height now means I'm seeing fewer cards at a time in the same space.
Keep up the good work and thanks!
