[0.5.0-beta.22] - 2023-06-29
Added

    UI: new menu entry to create UI-only playlists.
    UI: new lite mode to exclusively track UI-only playlists, thus behaving like a simple replacement for foo_plorg. Extends the current settings to disable/enable features, changing how the panel works at low level. i.e. no playlist files, no folder tracking, etc.

Changed

    UI: configurable playlist menus is now at 'Features...' submenu within the settings menu. No longer associated to "menu entries" since it now affects other settings.
    UI: settings menu, new playlist menu, keyboard shortcuts and filter buttons now follow the settings for shown/hidden features. i.e. if menu entries to edit tags are hidden, then all other features depending on it will also be hidden (like filtering or sorting by tag). (see above)

Removed
Fixed

    Playlist locks: menu entries not working properly for multiple selection mode (when lock was set by another component). Now mimics the behavior of single selection menu.
    UI: workaround for a SMP crash with some combinations of sizes drawing rounded boxes. This doesn't solve the underlying problem but at least bypass the crash and just omits painting the element.
    UI: another workaround for a SMP crash with some combinations of sizes drawing rounded boxes, this time aiming to avoid the previous situation by properly adjusting arc of rounded boxes whenever it's possible.

    UI: added manual sorting. It must be enabled on the sorting button and works independently to the automatic sorting methods. Playlist can be reordered by drag n' dropping within the panel or using the sorting submenu. It also works with multiple selection. Pinned playlists are ignored in this mode. Sorting indexes are stored at '.\js_data'.
    UI: configurable columns to display playlist metadata. Width, metadata, font size, order, num of columns, borders and colors can be set. In the case of playlist's size, a configurable unit may be set. The entire feature may be disabled using the configurable UI elements submenu.
    UI: added sorting by creation date.
    UI: added sorting by duration.
    UI: added configurable R. click mouse actions (like the previous L. click and Middle click ones).

    UI: filter header button is now highlighted whenever a filter is active, It follows the 'Also reset search filter' setting, thus not being highlighted while using the search filter if it's disabled.
    UI: added new menu entry to create a playlist from current selection (which does the same than drag n' drop + ALT).

    Keyboard shortcuts: pressing F7 will create a new empty playlist.
    Keyboard shortcuts: pressing F8 will cycle current view by category.

### Added
- UI: panel background can now use the now playing/selection art or an external file. Different proportion/filling settings available, along transparency.

- Search: in case current view is filtered by specific playlist (for ex. using the 'Playlist maintenance tools'), if there is a text on the search box, the results are also filtered by the search.
- UI: some improvements to menus while managing locked UI-only playlists (specially for native AutoPlaylists) or loaded playlists with UI-locks.
### Removed
### Fixed
- Search: current search did not update properly after adding/removing a playlist (for ex. cloning).

    UI: improvements to text shading depending on the background/art color.
    UI: mouse cursor now reflects when an internal drag n drop for manual sorting is not allowed. Selection is also shown using the inverted selection color (usually red/orange).
    UI: shift clicking on folder button will manually refresh the panel. Tooltip has been adjusted.
    UI: shift clicking on settings button will switch library tracking. Tooltip has been adjusted.
    Configuration: ALBUM ARTIST is now used instead of ARTIST by default (on new installations). This ensures better compatibility with classical music, where the artist is the actual performer but the album artist is the original composer/artist. To apply the change on existing installations, delete '[foobar_profile]\js_data\presets\global\globQuery.json' and '[foobar_profile]\foobar2000\js_data\presets\global\globTags.json' files. Further configuration may be needed via menus.

    XSP: XSP playlists not filtering duplicates -if enabled- when using shortcut actions or keyboard shortcut F3.

    UI: current view was vertically shifted sometimes after editing the query of an AutoPlaylist or Smart Playlist (instead of maintaining the position).
    UI: categories and tags not being sorted following current locale. i.e. "World" being shown before "foobar", due to uppercase usage, or "first" at the end due to "" usage. Now it follows the expected behavior: _first, foobar, World, ...
    UI: cosmetic internal drag n' drop fixes when releasing outside the allowed range.
    UI: workaround for GDI/SMP bugs or weird behaviors using text shading.
    UI: effects not being updated properly after releasing internal drag n drop for manual sorting on header or buttons.

@regor,

most definitely, I wouldn't even try to ask the user base as it is a fundamental feature in almost all programs nowadays!?
Georgia and Georgia-ReBORN have this update check and are displaying a hyperlink in the right bottom lower bar when a new
release has been published. When you click on the link, it opens the browser and redirects to the Github Releases page as you've shown in your animation.
So yes, just implement it =)

Also I have an auto update check and manual check as menu items in top menu:
Help > Theme > Updates > "Auto-check for theme updates" and "Check for latest theme update"
