To keep up with all the WordPress plugin and core updates on my many different sites, I have been using WP Remote to easily access and update the sites. This site was developed by Human Made Limited.

I also like the Site History feature for each site, so I can easily view what got updated and when so I can monitor changes in my sites.

I have tried other WordPress site management tools but this one is my favorite so far just for its simplicity and ease of use.
