Autocompletion for your tags when writing bearblog posts

I often could not remember little things about my tags, like is it "#book" or "#books", SO I made a plugin. Your available tags are listed under the "Attributes" dropdown on your new/edit post page. So as you type a tag, the plugin pulls from that list and compares what you typed to what's in the afformentioned list. By default, as long as the typed-word is IN the tag, the tag will be suggested. Like "blog" will match #blog, #blogger, and #bearblog (and will be sorted in that order). There are various configurations at the top of the script, including a block of CSS styles. The default orientation is vertical, but you can change --direction: to column to make it horizontal. For more on the configs, see the documentation written within the script's comments. You can also set styles in your dashboard theme. This plugin is fairly complex, dealing with dynamic user input and a dynamic header section. While I think I've fixed all the bugs, I will not be surprised if I left some hanging…
