Doesn’t work in WordPress.com Business plan

I run my blog on WordPress.com’s Business plan, which allows me to install and manage my site as it were in any conventional hosting.

However, WP.com forces its on admin bar, which is awful. There is an option to enabled classic admin bar, but right now, it’s completely broken in mine.

So, I’d like to know if there’s any other way to use/configure this plugin instead of admin bar. Is there?
