In the Finder, clicking the close button with the option key down closes all Finder windows. TotalFinder does not do this. I sometimes have many windows open and want to close them all, so this can be quite annoying. Maybe I’m missing something about TotalFinder that closes all the open windows?
You are right. This will work starting with the next version 1.4.24.
Good news! I should also have mentioned that option-clicking the minimize button has the same problem. Hope that will change too.
