Here is a horizontal video playlist from jnews

This fixes losing the player focus when user scroll down to select a different video to play.

Here are the changes needed to upgrade soledad video playlist to the next level.

1. 2 column and 3 column Video playlist cannot adjust the width between the player and the list.,

These 2 are PRESETS. The list width is too wide.

2. 1 column the video list goes below the player. That is not good. it is better to have a horizontal list under the player. This way no more problems for desktop and mobile display usability.

3. 2, 3 column video playlist needs the same option as in 2. above. Site owner can decide vertical or horizontal list for their playlist.

The reason why playlist is important because user can play all the videos on the list without needing to go in and out of single post. 

4. The video list section title. The best will be to show the playing now video title ie, A dynamic section heading,

For more advanced things like this. I am more than willing and I am sure other normal customers don't mind paying a little extra for premium features like this or you can raised the price once you have developed advanced features for soledad.

That goes back to what I have been saying.

The price for a single license vs multiple license packs business model will be a better way .

Soledad can have a basic model

and A Advanced version. This is similar to Preimium Gutenberg  and Elementor plugins.

Since you theme is more advanced and provide very flexible configuration options + many demos to choose from.

My requests are based on over the years all the lousy themes I have purchased that those developers FAILED TO REALIZE THEIR THEME DESIGN PROBLEMS.

Soledad Elementor Video Playlist 

1. Youtube Playlist does't display the latest video saved. Latest YT Video is placed at the bottom.

Is there a way to add sort to the list based on dates so the latest newest video will show at the top

2. Not very Mobile friendly

a. Soledad video playlist works fine on desktop.

But on Mobile phone, this vertical layout only creates viewing problem

When user scroll down the list he loses view of the player.

Solution. Add videos in the playlist a horizontal carousel right under the player

This design solves the problem of soledad video playlist on mobile phone problem.

JNEWS has the horizontal video playlist option but it fails to provide YT thumbnail 16x9 aspect ratio.
