I would very much like to create a Multi Commander for linux and OSX.
But the problem is that OSX , Linux and Windows all have different model for how working with files works. And how the GUI works.
So creating a version for linux or OSX is not an easy task. I would require a lot of work and then I would not have any time over for creating new features for the current Windows Version.
So right now the will not be a Linux or OSX version.
