One of the missing features in the 7-ZIP file manager that would make the GUI much easier would be to auto expand the destination folder used in the Copy To.. command. After selecting Copy To and then click selecting the ... button in the Copy dialog, and if the destination happens to be a folder, I have to manually expand that folder before seeing its contents. The reason this is so useful (something that WinRar has been doing for some time) is that I typically replace a folder using the contents of the archive and this extra step would allow me to delete the existing subfolder contents first rather than ovewriting it (without the extra click step of expandng the parent folder). This is a small feature but its so useful.
