Yes Gil, I well know you have presented all of these wonderful mods before, but I was thinking of making a simple 1,2,3,4,... type listing that could then be made a locked sticky at the top of one of the appropriate Boards, for all to easily access without having to search and wade through different Boards and long Threads. Perhaps even make the list in the order of best effect achieved, or maybe of easiest mods to do first etc.

Just a thought ...
