I´m searching for a Solution to implement a Scrollbar to the Descriptionbox on the MUI2 Component page. Because i got a large text to fill in.

To make the UI bigger is the last option what i want to use.
I tried to implement the UMUI, with the option MUIEx to use the big description option, but with no effect.

There is no native support for this but putting a edit box there and hacking the change notification a bit seems to work OK:
