The plugin is an awesome idea, but it horribly slows down the site and sometimes crashes it! Also, there is no option to hide the ugly tab that shows the number of active users. The display is mandatory. It spoils the look of the site, is a total eyesore and sticks out like a sore thumb.
The plugin is an awesome idea and I used to love the previous version. But ever since the update and the tab being made mandatory, I have been facing issues and even complaints from my readers. Uninstalled. Sorry about this.
