CiviDiscount Needs Improved Price Set Listings

Hi, suggested improvements for CiviDiscount Extension

1. price sets box lists even disabled price sets

2. suggest ways to reduce number of price sets displayed, as it can be overwhelming in number. perhaps eliminate perhaps: price sets not in use anywhere and/or price sets only used on events in the past

2. price set boxes on CiviDiscount are too small, hard to find and select the price sets. increase height as demonstrated in the attached.
