/* | |
* This script goes through your Gmail Inbox and finds recent emails where you | |
* were the last respondent. It applies a nice label to them, so you can | |
* see them in Priority Inbox or do something else. | |
* | |
* To remove and ignore an email thread, just remove the unrespondedLabel and | |
* apply the ignoreLabel. | |
* | |
* This is most effective when paired with a time-based script trigger. | |
* | |
* For installation instructions, read this blog post: | |
