Ok, not so much a feature request, more a suggestion. Might be a biggish job, but it would be better to change now rather than in the future where you might actually get round to implementing *gasp* right click copy/paste menues (Seriously though, I can't believe that hasn't been done yet! And yes, I know you can use the keyboard, but come on...)

While I couldn't swear by this, I'd reckon SWT would also speed up Limewire on older machines. At the very least, people wouldn't have to put up with Swing deciding not to work all of a sudden (usually when you're exhausting your memory I find) and having to restart the application.
