Add GUI buttons functionality for local save and load of Kodi playlist as .m3u file

[sdaau]

Hi - thanks for a great addon!

Describe the problem

Let's say, I've made a playlist, by right-clicking YouTube videos and doung Cast to Kodi/Queue item:

Now, if I by accident do a Cast to Kodi/Play now, it will - as expected - overwrite the current playlist.

Describe the solution you'd like

I would like to propose an additional button in the addon GUI (like on the screenshot above), which saves the current Kodi playlist, as a file on the computer, (for instance, that button could have a mouseover text "Save current Kodi playlist locally".

As far as I can tell, the default playlist for Kodi ( https://kodi.wiki/view/Basic_playlists ) is an .m3u file; and this file accepts plugin:// protocol URIs/links - for instance, from https://github.com/kodi-pvr/pvr.iptvsimple/blob/Nexus/README.md :

...
#EXTINF:-1 catchup="vod",Channel K
plugin://plugin.video.my-vod-addon/play/catalog/channels/d8659669-b964-414c-aa9c-e31d8d15696b
....

The only place I found these plugin:// protocol links to be mentioned on the Kodi wiki, is https://kodi.wiki/view/Dynamic_List_Content

So, having saved this .m3u file with plugin:// links locally, I could then copy it to Kodi, and play it directly in Kodi (which is great!).

But, I would also like to propose one more additional button in the addon GUI (like on the screenshot above), which then loads/imports a locally saved .m3u file as the current Kodi playlist, replacing the previously active playlist in Kodi (for instance, that button could have a mouseover text "Load/import local .m3u file as the current Kodi playlist" or similar).

Environment

• Cast Kodi version: 6.3.1
• Browser version: 96.0
• Kodi version: 19.2

Sorry, I'm not going to add this feature because the goal of Cast Kodi is only to send and control Kodi from a browser. The idea of saving a playlist is good, but it should be implemented in Kodi.
