The help file is illogically organized

In the help file there's mention of a "GPS simulator" feature and a "Measure in maps" features... there is however a red asterisk overlay on these page icons in the Additional Features section...

There is however no mention whatsoever if this means that it is only available in the Pro version.
If this is the case and that is the meaning of the asterisk overlay on the icon,
THEN PLEASE MOVE THESE PAGES TO THE PRO SECTION so that this is clear from the start and folks don't waste time downloading something that is advertised as if it's a default feature
(see https://wiki.openstreetmap.org/wiki/MB-Ruler)
when in fact it is only an after-registration feature.
