Yes, sir! Cold crashing encourages proteins, hop trub and yeast to settle to the bottom. Some beers like NE IPAs will remain hazy but this is usually by design. Main thing is crashing will help you drop hop trub out of suspension.
I still like to contain the hops as much as possible in the boil meaning the cleaner the wort you put into fermenter, the less you have to deal with. However, there are many brewers who dump it all in and worry about the sediment later on. Depends on your style.
