Changelog

[Unreleased]

Admin submenu items (Dashboard, Backups, Profiles) not created on install — <submenu> block in manifest was empty
Submenu items not created on update — added ensureSubmenuItems() using Joomla's MenuTable API with proper nested set positioning
Submenu icons not rendering in Joomla 6 — set menu_icon param for level 2+ items (Atum only renders img column icons for level 1)
CSS selector #menu → .main-nav for icon injection (Joomla 6 uses dynamic id="menu{moduleId}")
Use margin-inline-end instead of margin-right for RTL layout support

Dashboard submenu entry as default landing page with class:home icon
[DEFAULT_DIR] placeholder for portable backup directory configuration — resolves to administrator/components/com_mokosuitebackup/backups at runtime

checkDir AJAX endpoint for real-time directory permission checking
Web-accessible warning badge on backup download buttons when archive is inside web root
Inline security warning in FolderPicker when default directory is selected
Auto .htaccess and index.html protection for web-accessible backup directories on profile save and at backup time
Font Awesome 6 submenu icons via CSS injection in MokoSuiteBackupComponent::boot()
