  • Works

    This plugin seemed to work fine for me. I wish the timeline 'Rendering' was broken down somehow with more granularity. I have always wished for a tway to tell which crappy plugin is burning up all the time to render a page.

  • unobtrusive yet extremely helpful

    I don't understand why this fine little plugin doesn't have much more fans. It integrates nicely at the bottom edge of your site-display, offering some KPI at all times, ready to be popped open when more information is needed. Its waterfall diagram (titled "Timeline") helped me zoom in on a troublemaker in matter of moments; much more intuitive than quite a few alternatives I have tried before. Thank you, @Avram; may this live long and gain the audience it deserves.
