AFAIK Total Commander was fman's main motivation (IIRC the developer mentioned that on the bootstrapers.io forum). It'll be interesting to see how it evolves, but TBH i find Total Commander perfectly fine and i love how lightweight it is (...compare win10 calc with tc...) while providing a ton of features. And while i understand the (fman) author's point about lifetime licensing, i still prefer TC's lifetime license.
