On large sites with many authors working concurrently it can be very annoying to wait for your turn to publish. Also, not being able to cancel a publish job is very annoying.
Luckily, Ivan Sharamok has created a fantastic module which extends the publish dialog and lets you see which jobs are running and also cancel them if needed.

Btw. I’ve tested it with Sitecore 7 too and it works.
Looking forward to those publishing enhancements that are announced to be part of Sitecore 7.2.
