This plugin lets you as a network administrator add users to your sites without having to remember or look up the user’s login name. It replaces the input field with a comfortable dropdown menu, so you can choose between all existing users that are not yet added to the site.
Don’t worry about code overhead or performance issues, the plugin will only be loaded when a network admin screen is requested.

WPMU Network Site Users Dropdown

Replace the input field for adding existing users to a site with a more comfortable dropdown menu!

Syde

MultiSyde enhances the WordPress Multisite experience by addressing common usability challenges and streamlining network administration tasks. Developed by <a href="https://profiles.wordpress.org/syde/" rel="nofollow ugc">Syde</a> as both a practical tool and proof-of-concept for potential WordPress core improvements, with a focus on Multisite.
The plugin targets WordPress Multisite network administrators, developers, and organizations managing multiple WordPress sites. It focuses on targeted, high-impact enhancements rather than attempting to solve all Multisite challenges at once.
MultiSyde follows a modular architecture where each feature addresses specific pain points identified in <a href="https://core.trac.wordpress.org/tickets/active/" rel="nofollow ugc">WordPress Trac tickets</a> and community feedback. The plugin is actively developed and welcomes community contributions via the <a href="https://github.com/inpsyde/multisyde/" title="MultiSyde GitHub Repository" rel="nofollow ugc">GitHub repository</a>.
