We have a new app that will allow you to download, license and update all your aescripts + aeplugins tools in one click! It's something that many people have been asking for and we are really excited to finally have it available. However we need to test it first so we are asking for OS X users to give it a test. There will be a windows version once we work out the kinks on the mac version which will hopefully be soon.
You can download and discuss any issues here: http://bit.ly/1MY08Zv
