Not an essential - but a really nice daydream...

I'd love to be able to comment my code like this below and
have the option to make syntax hightlight for // comments appear in one
colour and the # commments in another.


// function to do something
function doSomething($target)
{
# this formats the target
$return = strtolower($target)

# this trims the target
$return = trim($return)

}

just a wish...

Probably easy to implement and no reason why /* */ comments couldn't have another colour as well.

I often use // for permanent comments and # for temporary where I will probably delete the comment.
