I just want to point out that your ADDT Pro "global variable scope" is directly related to your ADDT Con "More CPU/Memory Resources taken".
WA Plug Ins do "global variable scope" just fine, as long as the load order is proper. As your fellow "hard core programmer" said (what the heck are you loading.....). ADDT only worked because of bad loading practices :)
I provided a more detailed response to your post here: showthread.php?t=15274
