+THOUGHTS ON HISTORY:
+====================
+
+ * We need single history button, back/forward will complicate things.
+
+ * When we jump on dest link we should add current page and link to the history.
+
+ * When we jump on external link we should just add external link.
+
+ * It's enough to have 7 entries in history, too many entries complicates things.
+
+ * We should avoid duplicate entries in history. If we'll activate entry
+ that already exists (have the same title) we can just move it to the top.
