Copies all the commit messages and adds them as an unordered list into the Deploy Log Message text box.
On Pantheon if you have pulled changes to the test or live server, then you know it's up to you to manually enter the commit message. However it is useful to keep the same commit messages as the dev server so as to know which exact commits were included and when.
This extension lets you click a button to get all the commit messages that are ready to deploy and use those to create the commit message for the test or live server deployment. Like a way to auto generate useful commit messages.
