@MiningMarsh(View Post) it's still an issue if it wipes all your personal files, which are probably more important than protected system files to you.
Anyway, for certain reasons (talked about in many threads before, and on the previously requested elements wiki page), we won't add this. It makes saves rely on how the elements are implemented, if you set the .ctype of QRTZ and suddenly the next version changes what the ctype of qrtz does, that's a broken save. All the checks that would be necessary to fix this are too much, and we don't want a bunch of compatibility. Also, not everyone knows how to use the console, or should be required to know how in order to make good saves. TPT is already complicated enough to learn as it is. !set commands are probably too little, and lua is too much and exploitable. Also, signs are limited by length, i'm really not sure how much you could do anyway ...
