This is native support for quicklook, because qlmanage isn't good solution, for example u cannot to get preview for video (will be throw error).

• Adds three new Tauri commands: open_quicklook, toggle_quicklook, and update_quicklook
• Introduces QuickLook state management in the frontend to track when QuickLook is active

Yes, quicklook doesn't like a new threads, so smth like video will be crashed via qlmanage (as for me this cli for debugging or smth similar to)
Also my advice will be use some state manager like https://github.com/pmndrs/zustand or smth similar (u can eliminate props-hell)
We can create more reusable store (or sequence of stores)
I tried to start working on it but I don't have more time for investigating whole app.

Thanks for the suggestion! I will look into it and it's awesome you have done some investigation.

@ldm0 Is that ok PR for u?

Yes, this is a good feature, I am trying to understand it and tweak it.

For example, the event monitor you add are trying to propagate the arrow key event to cardinal main window(I think it's a nich catch to sync the behaviour with Finder), but currently it's not working on my mac. I am investgating the underlying issue.

By default quicklook has big priority and focus will be on quicklook. My trick need for add possibility when u make active main window (click on title, or click inside list of files) - use arrows for navigating by list of files and quicklook automatically updating. It's works on my old mac with intel (2015) and my current m3.
This some situation because main window - is tauri, but quicklook is native, and native will be has bigger priority.

Here small example how it works
