Scrollable list of indicicators needs to be more obvious

It is not obvious that there is a scrollable list with many indicators! You may want to resolve this by stating in the text field...

"Scroll down and select an indicator to add"

...instead of just...

"Select an indicator to add"

...as it is now. It will make the list more intuitive I believe and is not too much work to amend this text field rather than a GUI enhancement.
