/**
 * @inherit MauiKit::Controls::Page
 * @brief This control displays the file system entries in a given directory, allows subsequent browsing of the file hierarchy and exposes basic file handling functionality.
 *
 * This controls inherits from MauiKit Page, to checkout its inherited properties refer to the docs.
 * @see MauiKit::Page
 *
 * @image html filebrowser2.png "FileBrowser control"
 *
 * @section features Features
 *
 * This control exposes a series of convenient properties and functions for filtering and sorting, for creating new entries, perform searches, and modify the entries.
 *
 * There are two different possible ways to display the contents: Grid and List, using the `settings.viewType` property.
 * @see FMList::VIEW_TYPE
 *
 * More browsing properties can be tweaked via the exposed `settings` alias property.
 * @see settings
 *
 * Some basic file item actions are implemented by default, like copy, cut, rename and remove, and exposed as methods.
 * @see copy
 * @see cut
 * @see paste
 * @see remove
 *
 * @note This component functionality can be easily expanded to be more feature rich, see for example the Maui Index application.
 *
 * This control allows to perform recursive searches, or simple filtering of elements in the current location by using the search bar. Besides these two, the user can quickly start fly-typing within the browser, to jump quickly to a matching entry.
 *
 * @subsection shorcuts Shortcuts
 * This control supports multiple keyboard shortcuts, for selecting multiple elements, creating new entries, copying, deleting and renaming files.
 *
 * The supported keyboard shortcuts are:
 *
 * - `Ctrl + N` Create a new entry
 * - `Ctrl + F` Open the search bar
 * - `F5`  Refresh/reload the content
 * - `F2` Rename an entry
 * - `Ctrl + A` Select all the entries
 * - `Ctrl + N` Create a new entry
 * - `Ctrl + Shift + ← ↑ → ↓` Select items in any direction
 * - `Ctrl + Return` Open an entry
 * - `Ctrl + V` Paste element in the clipboard to the current location
 * - `Ctrl + X` Cut an entry
 * - `Ctrl + C` Copy an entry
 * - `Ctrl + Delete` Remove an entry
 * - `Ctrl + Backspace` Clear selection/Go back to previous location
 * - `Ctrl + Esc` Clear the selection/Clear the filter
 *
 * @section structure Structure
 *
 * This control inherits from MauiKit Page, so it has a header and footer. The header bar has a search field for performing searches, by default it is hidden.
 *
 * The footer bar by default has contextual buttons, depending on the current location. For example, for the trash location, it has contextual actions for emptying the trash can, etc.
 *
 * @warning It is recommended to not add elements to the footer or header bars, instead - if needed - wrap this control into a MauiKit Page, and utilize its toolbars.
