JSM Show Post Metadata

I've started recently to use this plugin to discover post meta values, I must say it's cleaner than other plugins I've used before.

Thanks for the latest update release 2.0.0, the ability to have post meta updated without having to load the page is pretty awesome.

I use the plugin almost everyday. I recommend it to anyone who wants to see what's in post meta.

Keep it up!

Useful and Very Clean Post Meta Viewer Plugin

It's great for letting me see hidden metadata without having to open up the database.  Plus, it's great for allowing non-technical users to see the information without the risk of sending them to the database.  

Super helpful tool!


I'm definitely not making full use of its potential but, for what I need it, it has proved to be dependable and very useful.



Thank you for sharing your work.
