Coupons - Courses Selection

When editing a coupon, the 'Courses' area is very tricky to use, the box is too small and seemingly not in any order. Can the box be made wider and one entry per row, in alphabetical order? Also surely only courses which have e-commerce switched on should be available to choose from and not every single course on the system, that would greatly help as we don't have that many e-commerce courses.
