The categorization of Options has made it harder to find things, because 
individual options are now concealed within a hierarchy and I don't see a way 
to help the user find where in the hierarchy an item lies.  For example, if I 
don't know how something was categorized, then I have to open folders and 
expose items in the hierarchy till I find it.  Just now I was looking for 
the "Modules" option, but I didn't know how it was categorized.  It was harder 
for me to find than it was before when everything was in a single list (and I 
could scan down the list till I saw "Modules"); I found it in folder "IDE 
Configuration" / "System".
It would help if this new options panel allowed a way to search for something 
in a way that is quicker than the user opening folders and visually scanning.  
For example, for the top node in the tree, you could add a menuitem "Find..." 
to its popup menu; also allow ^F to do the same thing from anywhere in the tree 
(also, on the main menu, enable menuitem Edit-->Find).  These commands would 
display the standard netbeans Find dialog and allow users to search the Options 
hierarchy.  When a "hit" occurs, the hierarchy would be opened down to that 
point and that node would be selected.  For example, in my case I could have 
searched for "modules".
