+
+The variable `triggers` is only used to check if in contains a particular
+value. Given that the number of keyboard shortcuts is starting to be
+significant, let&amp;#39;s future-proof the performances and use a `Set` instead of an
+`Array` instead.&lt;/pre&gt;

+      &lt;pre style=&#39;white-space:pre-wrap;width:81ex&#39;&gt;Use an io.ReadSeeker instead of an io.Reader to parse feeds
+
+This will allow to make use of func (*Reader) Seek, instead of re-recreating a
+new reader. It&amp;#39;s a large commit for a small change, but anything to simply the
+reader/buffer/ReadAll/… mess is a step in the right direction I think, and it
+should enable more follow-up simplifications.&lt;/pre&gt;

+- allow youtube urls to start with `www`
+- use `strings.Builder` instead of a `bytes.Buffer`
+- use a `strings.NewReader` instead of a `bytes.NewBufferString`
+- sprinkles a couple of `continue` to make the code-flow more obvious
+- inline calls to `inList`, and put their parameters in the right order
+- simplify isPixelTracker
+- simplify `isValidIframeSource`, by extracting the hostname and comparing it
+  directly, instead of using the full url and checking if it starts with
+  multiple variations of the same one (`//`, `http:`, `https://` multiplied by
+  ``/`www.`)
+- add a benchmark&lt;/pre&gt;
