Product comparison features

• Compare products table (product comparison site alternative that works on the pages you already browse): same specs on the same line, sort by price or spec (e.g. device memory in Gb), shows a badge for cheapest and best rated, order specs by dragging or buttons to move to bottom or top.

• History of previously ecommerce compared items are shown at the bottom and can be re-added or cleared. Notes are saved and restored
• Wipe all the saved data (chrome storage) with a click at the bottom
• Export to CSV (only Premium users, see below).
