2.0 (2015-01-15)

  • Integrated data into ‘themes.php’ table
  • Moved from storing data in option to transient
  • Changed main filename resulting in a deactivation after update


  • fix + update of tablesort js library
  • tabbed settings
  • fixes for WP 3.5
  • move of the development repo to GitHub


  • Added a check for making sure the Theme Files are present, and will display a message if there is a site using a theme that no longer exists


  • Updated for 3.4. Because of the massive Theme info API change with 3.4, this plugin now REQURES 3.4+ to function

1.2 – 1.6

  • Unknown exactly because I wasn’t maintaining this plugin for public use for these versions, but the following occurred in here:
    • Properly enqueue scripts
    • Updated for 3.1. Then later dropped support for anything below 3.4
    • fixed lots of notices and warnings
    • properly store data after the 3.3 add_site_option changes


  • Adding Show/Hide blogs on the administrative page.
