DiskMaster
http://kazong.privat.t-online.de/DM2V34.zip last version that works under 1.3 kickstart.
It's one of the best file managers on the Amiga and highly, highly customizable. Probably would be a better choice over Dopus.
Still a fun project and hope we'll see a release fairly soon
And other fine Shell replacements (apart from ZShell): WShell and CSH
