I always preferred DirWork, by Chris Hames. Got it back when it was free waaay back in the day, used it through all the free versions, then when it went commercial I got lucky enough to find it on a coverdisk (I was a very, very poor Amiga user back in the day, couldn't afford Dopus).
They all do pretty much the same things: allow you faster access to copy files, move files, rename, sort, unarchive, view pictures, and run many, many other tasks. They can be a bit complex to initially configure, but once done it's one of those "couldn't live without it" tools. I set my DirWork to run by pressing the * key on the numeric keypad right in my startup, so it's always available (starts in sleep mode).
If you go to Google and do an image search for "DirWork Amiga" or "Dopus Amiga" you should find dozens and dozens of screenshots of different people's configurations, which, just like Amiga's, everyone's is unique.
