This plugin helps you deactivate the update for the plugins you don’t want to update! 
Let’s say you are working on a website and you modified several plugins to make them work the way you want them to. 
If you (or your client) later updates the plugin, all the changes you made will be lost. 
This plugin will help you in solving this issue. 
It will let you select for which plugins you want to disable updates. You can then leave a note to explain the changes you made.
Please note: 
It’s strongly recommended that you keep your WordPress plugins up to date. 
If you skip plugin updates, you could expose your website to critical security issues.

Ever have one erroneously entered custom field name confuse all of your users and you just can’t figure out how to get rid of it? Delete Custom Fields will let you delete every instance of a custom field from your site. Once your remove a custom field using this plugin it will not appear in your list of custom fields when you edit a post or page.

Delete Custom Fields

Doesn't show all custom fields, though (even if you choose Show Hidden) - would be nice to have them as a list instead of a dropdown, but otherwise it does what it promises.

Works

Remove every instance of a custom field from your site.
