XXX are hidden. Enable them in the Map Data pane, or click HERE.

Description

The message says:

XXX are hidden. Enable them in the Map Data pane.

The user thinks:

Hey, that's a lot of work, asking me to open up the Map Data pane. (Yes even if I opened it earlier in the day.)

Therefore the message could say:

XXX are hidden. Enable them in the Map Data pane, or click HERE.

(which would run some javascript to change the setting, without anybody needing to open the Map Data pane.)
