v1.6.0

Added

• Form/translations element — locale tabs for translatable entity fields (_translations.{locale}.* field names); documentation in docs/HELPERS.md and docs/CONFIGURATION.md
• simple layout — minimal layout for embedded file browser (TinyMCE image picker iframe)
• FormHelper (dateRange): value as [$from, $to] or ['from' => …, 'to' => …]; valueFrom / valueTo for separate defaults
• Tests for the translations element and TinyMCE browseImages layout behavior

Changed

• File Manager: browseImages / browseFiles use simple layout for full-page requests (e.g. TinyMCE URL dialog) and ajax for modal loads
• TinyMCE editor: image picker opens browseImages via windowManager.openUrl with postMessage selection
• Update card background styles in CSS for improved visual consistency in light and dark themes
• Change sidebar toggle icon to bi-layout-sidebar-inset
• Refactor pageHeader layout and update styles for improved responsiveness and padding in page-header and page-content sections

Fixed

• File Manager: preserve folder and target query params when filtering files in the browse view
