On Stack Exchange sites, edits that are made within 5 minutes  of posting a question / answer aren't counted.

For example, if you post a new answer, and edit it after 5 minutes grace period, then this is how it'll look like:

![with edited link][1]

If you make the edit *within* the 5-minutes period, then it'll look like:

![without edited link][2]

It'd be great if you can see a countdown timer that starts counting down immediately *after* you post a question / answer. Might be pointless, but what do you think?
