Today I added the following features:
1 – An options page.
2 – The ability to change the name of the XML file. This includes some error checking to be sure that the filename will never be blank and a function that deletes the old XML file in the event that the filename changes (both from the XML and the wp-content directory).
3 – The ability to upload an image to be used as an icon in the toolbar. This image is optional. The absence of this image will result in the toolbar using a default image. This feature includes a function that base64 encodes the image so it can be added as text to the XML file. If the image is changed (either by changing the URL for the image in the supplied field or leaving the field blank) then the old image is deleted (both from the XML and the wp-content directory).
I think this plugin has matured enough to be elevated to version 1.0 status. You can download the latest version from my website: https://nothing.golddave.com/?page_id=78
