Highlighting within brackets

Hi there, 

Currently in sublime you get a little marker to show the start and end of any bracket you are within.  () [] or {} 

It's handy but when you are in a large file it can be a bit like Where's Wally trying to find the other one sometimes, so I thought it might be nice if you had the option to slightly highlight that section so it's really easy to see where you are. 

Just thought this might be kinda cool. 

Thanks

Pete
