Since requests started here...
1. Now when unpacking password-protected 7z-archive with encrypted filenames, MC asks password 3 times. It would be good to see password prompt only once.
2. Now if archive contains sub-archives, MC only goes inside top-level archive. Then it unpacks packed archive and (seems to) redirect it to the system although it is supported by MC. E.g. if there is a zip inside 7z, MC will go into 7z, but zip will be opened in Winows' Explorer. If there's a rar inside 7z, nothing will happen (probably because there is no app associated with *.rar files in my system). So it would be great if MC could go through all sub-archives.
3. External archive profiles.
4. Some kind of status info for a focused file in the List mode.
