feature request: Allow favoriting more than 7 items in the marketplace

As stated in title. The limit is currently 7. It could be similar to how the 'Send Supplies' feature lets you pin specific supplies in the settings. In my mind, I imagine a new row of additional items in the existing marketplace window based on what you choose in the settings.

Adding another marketplace related feature request, the ability to hide the 'High Value', 'Frequently Traded', and 'In Demand' sections which I never use.
