Open archives as read-only by default: If this is turned on, when you navigate to an existing archive it will automatically be treated as read-only by Opus. You will not be able to make changes to the contents of the archive without turning off
read-only mode. (This works with the internal Zip support as well as 7z, RAR, TAR, etc. archives handled by the official Archives plugin. Support within third-party VFS plugins may vary.)
