Hi @ThomasLandauer

Shouldn't this be the following?

Suggested change

	Profiling Applications and Stopwatch
	Profiling Applications with Stopwatch

[ThomasLandauer]

I'm using the Stopwatch to measure how long a Console Command is taking to run. That's it. I wouldn't call that "profiling" - would you? So the message I'm trying to get across with the word "and" is: "It is a stopwatch; you can use it for profiling; but you can also just use it as a, well, stopwatch."
But I must admit that this message certainly doesn't get across fully ;-)

Thomas, I thank your for proposing this but I'm going to close it as "won't merge". The reason is that this page already includes the "stopwatch" word tens of times. Here are some of those occurrences:

Thanks for understanding!

I have 3 counter arguments:

• When searching for "symfony stopwatch" Google is still showing https://symfony.com/doc/3.2/components/stopwatch.html as top result, and the current page not at all. This is probably due to "stopwatch" not being a heading.
• When searching for "stopwatch" at Symfony's internal search at https://symfony.com/doc/current/index.html there's no "stopwatch" header (only fine print) which is a shame.
• What harm is it doing to include the very component's name in the header?
