ExpressionEngine accessories are kind of cool. To quote Kenny Meyers:
Accessories are simple. They have a very specific function. They’re little tabs that appear on the bottom of the Control Panel that contain information for the user. There are ones that display site analytics. There are some that tell you how many comments are marked as spam. You can, theoretically, create a client contact form. There are ones that contain an RSS Feed of your favorite EE site.
The only requirement for accessories is that they’re in the Control Panel, and they appear as little tabs at the bottom.
But what if all you need is a place to communicate simple information to your Control Panel members, like announcements, tutorials, helpful links, and so on?
Well, you could write an accessory yourself, it’s really simple. But what if the content in that accessory is likely to change after you hand off your code to the client? You don’t want to adjust that accessory every time they have new information, that would be exhausting.
