Hi, these are my initial thoughts.

I think everything so far is pretty great so far.

I like the layout, the ease of use, and the choice to give basic info and an expand button. 

I haven't spent a huge amount of time with it yet, but everything is fairly intuitive.

I only have one issue so far. I would like to see the ability to SORT magic items by rarity rather than a filter which only gives you the option to CHOOSE the rarity. In general my thoughts are that there should be the option to sort whenever it is possible.

Thanks for all your hard work.

I was just about to post this very thing.  It's a good thing I looked it up first.

I agree wholeheartedly.  A new column for rarity would be great to sort by.
