Hi,
I'd like to thank Rico for this little jewel.

If you're still looking for suggestions, I have an idea which you may like.
Since the person who will use BW5Tweaker will use it to do only one of 3 things: Read, Write or both (i.e. copy), why not remove (gray out) the options that are not valid for the selected operation?
I'm suggesting a remake of the interface, where the user MUST first select the operation (Read, Write, Copy), then create 2 tabs: Read and Write which contain all the options for the respective operation ONLY. So if the user wants to Read a CD, the Write tab will not be available and vice-versa. Of course both tabs will be available if a Copy operation is requested, or perhaps you can create a 3rd tab which contains both read and write options, plus any options applicable only to a copy operation.
I think it would make BW5Tweaker a bit more user-friendly for those of us who only use it occasionally (and forget a lot by the next time they need to use it).
What do you think?
