I used it a little. It's nice because it remembers where you were last, unless you don't want it to. Also, you can either explore two directories at once, one in each column, or see file previews of files in the unused column.
When opening a file from this, it behaves as if you were directly in that directory when you opened it. It will stay in back ground until you are done using the file. I'm not sure if it works with many programs, I've only used it to go through some code along with Vim.
The thing I'd like to see if when previewing files, it would be nice to be able to have syntax highlight and such.
I use vifm off and on for moving files from one dir to another. (IIRC there were some issues with the latest version on OSX, perhaps sourceforge does not have the latest, and brew picks from there).
