It works well but there are some unfortunate design issues on the admin side

The plug-in works well enough. It did what I needed to do and the options gave me decent control over the look of the accordion.

However, there are a few things I found a annoying, that I offer here as a critique to help the authors improve the plug-in:
1. There is really no need to make the button that appears on the edit page and edit post menus bright red. It’s pretty loud and annoying, especially since I’d guess that most users of this plug-in use the accordion feature on one or a handful of pages and then have to be annoyed by the loud button that we mostly are not using. Most other plug-ins I use that put up a button here put up a gray button with maybe a small, colored icon.
2. Overall the color scheme for the edit interface is a bit loud: bright, saturated colors that don’t actually make the plug-in easier to use.
3. The quantity of advertising on the admin interface page is really a bit over the top. I understand the need to find ways to make money on the time invested in building a good plug-in that people then use for free, but the advertising at the top of the edit accordion page fills almost the entire screen on even a large monitor and there’s a similar quantity of advertising at the bottom of the page.
3. I’d also encourage the plug-in authors to get some help with proof-reading by someone who is better at English. There are spelling and grammar issues all over the place in the documentation and the user interface. I didn’t take any stars off for this since I suspect the authors are not native English speakers and I know how hard it is to write well in a foreign language, but the plug-in would probably get more users if this issue was addressed.
