Shouldn't there be an option to switch between QuickLook and Seer?

[yaira2]

I'm undecided, we'll definitely want an option once we add a built-in preview feature but until then, I'm not sure if there is a valid use case where a user has both apps installed at the same time.

There may be situations where the user would like to select a preview tool if we support PowerToys Peek, but it certainly may not be necessary just yet.

LGTM

There may be situations where the user would like to select a preview tool if we support PowerToys Peek, but it certainly may not be necessary just yet.

We can work around this by putting PowerToys Peek as the last if statement, this way, if another provider is detected we know it's preferred.
