Extend length of Media Browser preview ?

Hey folks,
 
As the title suggests - is there a preference / hack / registry setting / tweak for extending the length of the preview in the media browser ? Seems to be stuck at about a minute or so. Tis a shame because I'd love to use the browser for listening back to my library of 'skits' as I call them - short, prototype, improvised ideas that I slap together quick as a concept test of sorts.
 
Trying to avoid using an external audio browser as I much prefer controlling / adding effects / sending to different monitors when auditioning audio through Sonar.
 
As a bonus question - can I change the ugly blue text in the browser ? Always looks kinda fuzzy to me for some reason.
 
Thanks for reading, best wishes to all!
