Auction: shopping list + zen mode

[Arctomachine]

Brief feature description
Major improvement for auction experience
Shopping list: while browsing auction, press + button to add this item to your shopping list for later.
Zen mode: remove everything from current tab. No description, no filter, no sort, no comparison, no collapsed tabs. Only leave timer and items from shopping list. Maybe a button to refresh page (same effect as pressing on current tab repeatedly).

Add a image as an example (advanced + optional)
Step 1: browse auction and find what we like. Press + on them.

Step 2: in this example we chose copper shoulders of demolition and trident of conflict. Buttons on selected items turn into X instead to remove from shopping list (requires confirmation)

Step 3: when done browsing, switch to zen mode. No clutter, only our chosen items to pay attention to. Spam refresh button and track bids almost in real time.
