Add option to enable "Prevent Closing" (Pinned) by default

[chengdd1987]

Feature Request

I would like to request a setting option to enable "Prevent Closing" (Pinned mode) by default when opening a preview window.

Current Behavior

Currently, users need to manually click the pin button on the toolbar to prevent the preview window from switching content when
selecting different files. This requires an extra click every time.

Proposed Solution

Add a configuration option (e.g., in settings or config file) to set Pinned = true by default when a new preview window is created.

Example setting:

True

Or a toggle in the settings UI:

• Pinned by default - Keep preview window content fixed when switching files

Use Case

Some users prefer to keep the preview window content unchanged while browsing through files, opening new preview windows for each file
instead of reusing the same window. Having this option enabled by default would save the extra click on the pin button every time.

Additional Notes

Currently, the pin button is one-way only (cannot be unchecked once pinned), which is fine. This feature request is simply about
having the pinned state enabled automatically on window creation.

I have to say that I don't really get your use case. What prevents you from pressing enter instead of spacebar and therefore using the intended default (persistent) viewer?
How would you use this feature? Open many files by going "down space down space ..."? And then closing them one by another by pressing X in the corner?

I don’t deny that some people might use it this way—just like a regular application: double-click to open and press X to close. The only difference is that QuickLook is opened with the Space key.
