In regard of that directory button, I didn't even notice it myself. Jose will take care of it hopefully. Nice find.
In regard of the quick reply - nice suggestion, will be certainly considered. But then of the negative side of things. You are reading the beginning of the thread (top of the page) and would like to reply quickly. You click on the button and it does two functions: activates the reply field AND brings you fast to the bottom of the page. If you didn't have that, you would have to scroll down to the bottom by yourself. Which would take more time: scrolling down or auto-redirecting?
