Rollerblade - a dead simple way for your clients to leave visual feedback on your WP site, creating information-rich tickets for you to track reports.

Activate the Rollerblade tool by clicking the icon. The icon appears only for the user roles you authorize in the plugin settings. (You can also show it for visitors that are not logged in, if you'd like).
Rollerblade is a tool that you can use to easily create issue reports and tickets for your team, right from an in-line interface on your WordPress installation.
Here’s the Demo:
