No "loading..." overlay to indicate the the Marilyn markers are being updated
Deal more gracefully with the problem of too many
markers when you're zoomed out
I used an older version of the Relative Hills of
Britain, so there are actually only 1542 Marilyns here
rather than 1554 - I need to update this at some point.
Lots more functionality would be good; e.g. links to pictures, allow you to mark the ones you've climbed, etc.
