Currently iControlWP supports all standard features as if those sites were normal WordPress sites. You can:
- Perform WordPress Database Optimization
- Install WordPress Plugins and Themes
- Uninstall WordPress Plugins and Themes
When it comes to activating and deactivating themes, it's a little different. Since you're managing the Super Admin side of the site, the actions are slightly different.
For Themes, you are "enabling" / "allowing" them, or the opposite. You do not activate or deactivate the theme on sub-sites.
For Plugins, you are activating / deactivating them and this will impact sub-sites depending on how the plugins have been programmed and designed.
Note: Management of sub-sites in a WordPress Multisite (WPMS) site are not currently supported in iControlWP.
