front: A few more time travel tweaks

I can never get it all in a single commit.

But I compensate by some times putting multiple unrelated things in the
same commit.

-            <p>Some features do not have time travel support (comment
-            spotting and DHCP map at the moment). We also lack
-            compatible SNMP data for the first day or so, so you'll
-            only have ping data for the first day of TG15.</p>
-            <p>It could take some time to load a specific point in time
-            for the first time. See "About performance" under the help
-            menu for more information.</p>
-            <p>You can also step backwards and forwards in time, stop
-            and start replay and go back to real time using keyboard
-            shortcuts. See the help menu for an overview of keyboard
-            shortcuts.</p>
+	    <p>Time travel allows you to see the state of the network at a
+	    given time, and even fast forward or rewind on the fly with
+	    keyboard shortcuts (See the 'keyboard shortcuts' help
+	    section).</p>
+	    <p>Some features might not work perfectly with time travel, but
+	    you should get a pretty good idea of what went on.</p>
+	    <p>While we have more detailed data, time travel is limited to
+	    five minute intervals by default for performance reasons.</p>
