I <3 Speed Download

It's 25 bucks, which I consider borderline extortion for a shareware app, but man is it good. Speed Download lights up my internet connection like nobody's business. It can saturate my cable connection, besting Safari for the same download by almost 10-fold.
The only quibble I have with Speed Download besides the price is the developer's fascination with red as a primary color for Every. Single. Icon. Hello, Apple UI guidlines?
