The sidebar and all panels are open. 
You can click on the arrow to the right of each label to open or close the panel. You can also sort the panels to be in the order you want. The open status and sort order are saved to your user account.

Reviews
It’s a very useful and informative plugin when you’re doing your own PHP developments on Wordpress. But i noticed that it was delaying page load by at least 3 seconds when it’s active (when you’re logged as admin)! So I removed it. I didn’t investigated further, may be it’s a combination of using this plugin with GeneratePress ?
I was just looking for a tool like this, found a bunch that are outdated. They might work but they’re still kinda old and their functionality didn’t look as complete as this one. This one doesn’t look maintained either, but it loads, activates, and works perfectly in 4.8.2.
Wow, great info, more than just templates.
Get it and review it here!

I dearly love this plugin. It’s such a relief to know if you’re using the right template file or not. One of my favorite plugins by far.

This plugin is going into my dev toolbox for all my projects. Love that it not only shows the template used, but also lists all the scripts, widgets, additional files, and other relevant info. Super useful for getting a quick overview of what’s going on under the hood.
