I have been asked to include a number of less common tags. I have now implemented a way of creating your own. To find out more about it you can read my tutorial
There is also a feature that is used to create and store posts the can be then used as a template/canned reply etc. It is also great because it gives you a backup of the post, and a friendly environment in which to write it. Some people have found other uses for it, such as a note taker.
The other change to the extension was I changed all the icons to those I had created for the Pastel SVG icon set.
