This plugin is a ‘swiss army knife’ of custom fields. It allows you to manipulate them to make it easy the testing and debugging of applications.
This plugin was built in a moment of desperation when I couldn’t access phpMyAdmin in a mu website. 
I absolutely needed to manipulate the custom fields for testing and debugging, version 1.0 was up in 4 hours. 
In the following months I realized how useful the plugin was and couldn’t work anymore without it. It had become part of my standard toolset.
Features: 
1 Read/write/delete options, user fields and post fields. 
2 Populate the field with an empty array. 
3 Insert a date string and translate it into a timestamp or vice versa to emulate specific dates. 
4 Change name to a field. 
5 Copy any field’s content to any other field (for example, option to user field) even of a different name.
You can contribute to the plugin or just study the code on the <a href="https://github.com/daprela/dapre-custom-fields-tools/" rel="nofollow ugc">Github repo</a>.

“Quick Empty Trash” is a small utility plugin that saves you time when emptying the trash for any post type. It adds an ’empty trash’ button to every post type’s list table, so that you can empty the trash for that post type without having to load the list of trashed posts first. This helps if you have a very slow-loading dashboard or if you just feel like saving yourself an extra page load in order to perform a simple action.
There are no settings to configure – just activate the plugin and the button will appear for you.
