It has been my daily driver for almost a decade, when my license for Servant Salamander (from altap.cz) expired. I like the configurability with external tools apart from rock solid core functionality. I would like to see Everything (from voidtools) Integration like in Total Commander.

And now is freeware. I don't know if that is a good or a bad thing (will they keep updating it?).

Salamander last update was 07/01/2019 so I really doubt it. Would not need it anymore though, considering advantages of Doublecmd and that is in active development since 2007.

Any real world accounts as how it compares to Autohotkey?
