🚀 Feature: Add "next item" in the preview window

[PhunkyBob]

🔖 Feature description

When I'm in the preview window (because the file is an image for instance), there are buttons "previous item" on the left and "next item" on the right that allow to go to the preview of the preview / next file having a preview available in the current folder.

🎤 Pitch

I share a folder with 50 pictures and I send the link to someone.
If this person wants to see quickly all the pictures:

Without this feature

• He clicks on the "preview" button of the first picture.
• He closes the preview.
• If he have already seen several pictures, he tries to remember what was the last picture he saw ("IMG_20240830245206.jpg" or "IMG_20240830245232.jpg"?).
• He clicks on the "preview" button of the next picture he thinks it is.
• And so on...

or

• He download the folder as a giant file.
• Unzip.
• He uses his internal picture browser.
• He deletes the folder.
• He deletes the file.

With this feature

• He clicks on the "preview" button of the first picture.
• In the "preview" window he clicks "next", "next", "next", ... until ha have seen all pictures.
• DONE!
