this is not quite true, there is an optional suggestions pane (currently behind
a flag) which would add another dot. However this is perhaps good enough for now
(can be revisited if the suggestions page ever becomes default).

this string doesn't make sense if the length is actually 0. I would change it to
"... exactly one selected tile page." (same above)
