I hear you. I wanted the plugin to have many more fonts available, as well.
The problem is that, because of the nature of the plugin (which uses server resources to create images), we need to include a special font file for every image we add. These files happen to be very big in size.
If we included a third font, the plugin file would be so big, that the WordPress uploader wouldn't accept it, so most people wouldn't be able to use the plugin.
I'll see if something can be done about it.
