Dec 1, 2025December 2025: Focused on usability, visual consistency, and test coverage for CollaboraOnline/online. Key outcomes include: (1) new select element interaction that shows options when the associated arrow is clicked; (2) robust fix for the resize handle to avoid interfering with row selection in dense UIs; (3) improved dark mode visibility with a clearly visible border around the styles view; (4) styling consistency enhancements via a dedicated CSS variable for the sidebar header height and refined selectors for notebookbar and iconviews; and (5) expanded UI regression tests for writer styles view expander, Chart Wizard width, and Page Style width to guard against regressions. Documentation also clarifies that resizeObserver observes the iconview (not the dropdown) and explains the implications of height changes. This combination reduces UI regressions, improves discoverability and usability in dark mode, and strengthens maintainability through better styling conventions and test coverage.
