Feature details

Can you guys make the Description Box Bigger? so the text gets a line break (or whatever it is called sorry) so you can get the full description without having to scroll sideways. For example like the Tags box.
Kinda annoying to need to Press "Preview" button to see full Description, also annoying to make it scroll sideways since its way to fast.
I'm not smart enough at the moment to do it myself to be honest.
Well if maybe someone could get me into the right direction , i will try to do it myself, since i at least was able to successfully build it, so learning more about it wont hurt i guess.

Additional information (optional)

I tried already searching the sources, but only found "description" for strings and such, but nothing .css like so im quite lost myself :(
also if this is an extension thing, sorry.
