CKEditor Contextual adds a configurable contextual (balloon) toolbar to CKEditor 5: when text is selected, a small toolbar appears at the selection with the buttons you choose, a fast in-context way to apply formatting without moving to the main toolbar. The button set is configured per text format using the same drag-and-drop builder as the main CKEditor toolbar, and only buttons whose plugins are enabled for that format are offered - the list tracks the main toolbar as you edit it. The balloon reuses the editor's own button components, so they stay in sync with the selection (active states, dropdowns), it hides when the selection collapses or the editor loses focus, and a "Contextual tools" toolbar button both enables the feature and toggles the balloon on or off while editing.
The Domain User Login module provides a seamless, stateless single sign-on (SSO) experience for administrators navigating across different domains in a multisite setup.
