Right now editing the product page description for an app is pretty frustrating because the textarea is only 3 lines long. For a field that is capable of holding 4000 chars, thats a considerable mismatch.
The consequence is when trying to select text and move around, you can overshoot by quite a lot because the smaller a field get, the more magnified mouse movements become (on OS X at least).
It's a small thing, but just making this field 10 or 15 lines long would go along way here.
(Bonus: Adding some minimal markup ability so we can make our product pages look beautiful would be much appreciated as well. Github flavored markdown is an excellent example of how this can be done.)
