Sometimes I just want to preview what's inside, WinRAR and 7zip seem to support hover preview archive.
You can add {foldercontents} to the infotip for the archive types, or the Archives file type group, under Settings > File Types.
But keep in mind that will cause the archive to be opened if the mouse is left over it and that, with large archives or ones containing installers, may cause your antivirus to freeze Opus for a long time while the archive is scanned sometimes.
Oops, I forgot the infotip. I don't preview larger archives because I can't see the progress.
Edit: Maybe adding some settings in the File Types to Prefs for jumping will be more friendly and easier to find?
