Feature request: Multi-open protection

Sometimes, when I’m organizing files into directories, I will have selected many tens of files in a folder in order to drag them into a new folder. If I happen to double click or press enter, TotalFinder will open every single file in its associated application, usually firing up 5 or more applications with tens of windows that I have to go and then close.

What would be great is if there was an option to bring up a confirmation dialog before going ahead and opening all files.

Especially in the case where files with different extensions have been selected.
