add minify feature in output class?

hi all,

please correct me if i am wrong, but i think CI doesnt have a minify feature for removing the whitespace chars from the html output before sending it to the browser, right?

i see there are numerous libraries out there , but why not have one in the CI "core" as well? it would definitely be useful , and shouldnt be that complicated as well, unless i am missing something here 

and - needless to say - many thanks for the wonderful CI
