Yeah...preview your post
It's not a simple thing to just add a new idea for a feature. Someone has to write a program or script, test it and install it. Development for these new scripts can be a lengthy, challenging, frustrating task... For the most part, End user webmasters just go to the PHP download site and choose what's there that they want for their site. If you are volunteering to write the code, go for it! It does sound like a pretty good idea...that whole pop up "are you sure you want to post this" thing but again...previewing your post will work just as well.
