Masonry Subtitles

Dear community and support

I have extensive Masonry Galleries on our Website and would like to use my comments when displaying the gallery both in the overview as well as in the Lightbox.

For this, I have manually added comments, directly underneath the pictures in the Masonry editor. These comments are additional to the file title as per upload into the media center (which seem to be used as standard for this purpose).

Current behavior (Desktop) is:
– On MOUSE STILL: “Tooltip” showing the file name as per media center upload (imported as “Title” into the Masonry Gallery)
– On MOUSE OVER: Comment (as defined underneath the picture when editing the Masonry Gallery) appearing underneath the picture
Current behavior (Mobile, Portrait) is:
– On OPENING the Gallery: Comment appearing underneath picture (and sometimes hiding most of the picture unfortunately)

Intended behavior (Desktop) would be:
– On MOUSE STILL: “Tooltip” showing the COMMENT (as defined when editing the Masonry Gallery) instead of the title
– On MOUSE OVER: Nothing (I know, I can just de-activate the comments/title in the Masonry Options)
– On OPENING THE LIGHTBOX: Showing the COMMENT instead of the title

Questions:
1) How do I make sure my manually added comments (subtitles) are visible as “Tooltip” when hovering over the picture? I used to add some code in the functions.php file to fix this but it doesn’t work any more with the current Enfold version
2) How can I make sure the COMMENT appears when opening the Lightbox of a picture (instead of the ‘title’)
3) (How) is it possible to turn off masonry gallery comments (subtitles) in the mobile view? My comments (subtitles) relate to artworks and are quite extensive. Hence, they hide almost every picture in the mobile view (e.g. mobile portrait view) if they are activated.

Thanks for your help
