When you hover (move mouse under) the function name with 'CTRL' button pressed\
IDE shows the tool tip. But if it contains a lot of text there is no way to read the information that is not visible currently.
I this it'll be very useful to add scrolling there.

Do you mean in editor ?
Reply from Mikhail :
Yes. If I am writing PHP code :
and trying to get information about strpos function it shows tool tip
and it is impossible to scroll text in helper window
