Discussions panel size in BI Launchpad

Hi All ,

We enabled Discussions options in CMC The entered comments are not properly getting displayed and scroll bar in that panel is not proper .Where can we change the size of the Discussions panel .

Can we call comments entered with query builder or somewhere to list all the comments entered by user for a report .Please observe below screenshot. Can we maximize this panel .

Image may be NSFW.
Clik here to view.

Thanks .
