The initial rectangular area when you open Adobe Reader X without opening a document is very useful since you can choose to open from there a recent file or Acrobat.com services. It would be even better, however, if its colors would change according to the selected Preferences > Accessibility > Document Color Options. Also, I could use the option to increase its font size, but just being able to change its colors would help a lot. I do not know if this is the place to make this suggestion, if not, please let me know where I should post it.
