Maybe one hint to improve the Plesk GUI: Why don't you integrate a lot more tooltips to give more explanations to the parameters?! Each and every setting should be explained on "mouse over" ...
This tool is great for this: https://github.com/qTip2/qTip2 and provides nicer tooltips than the one I have seen in Plesk so far.
Thank you for your input! We will consider this functionality in upcoming releases if it will be popular.
