appengine-multi-delete
Chrome plugin to allow deleting more than one appengine version at a time.
This is a HACK. It will likely stop working on the slightest UI change google makes to the appengine API! It works for me but I suggest you check all code first before using this against your production environment!
Installation
This is a chrome extension, so download this into a local directory, enable developer mode in chrome, load this as an "unpacked extension", browse to the versions page of your appengine application ...
Usage
On the versions page you should now see new checkboxes and a new button to delete selected versions (the ones with clicked checkboxes). If you click the button it will pop up a confirmation dialog and then proceed to open each delete page and click its confirmation button.
