0.5.3: the card stays visible when a marketplace opens a listing in a pop-up window (CSFloat). On some sites, it moves to another corner so it no longer hides the buy button. On narrow screens, it spans the full width at the bottom.

0.5.2: new name, "CS2 Price Checker – Veriloot". After five cards have shown you a cheaper price elsewhere, a small "Rate the extension" link appears at the bottom of the card; one click on it, or on "Don't ask again", removes it for good. The counter stays in your browser. Fix: after navigating within the same marketplace, the previous card could stay on screen.
