So there're these helpful floating previews on the few latest macOS version. But I can't seem to find any way to increase the duration of a preview. Is it even possible? Quite often it's sliding away while I'm looking for a window to drop it to. And it's very frustrating.

I have found a way to configure the duration of a screenshot preview.

 defaults write com.apple.screencaptureui "thumbnailExpiration" -float 30 && killall SystemUIServer

Works like a charm
