1)I would really welcome a File Manager mode. I mean a local 2 pane mode.
WinSCP would be a great free alternative of Total Commander.
I like the interface of WinSCP.
I see, there would be not needed big changes to allow 2 local panes.
2) Customizable keyboard shortcuts.
This would make possible to have similar keyboard shortcuts like Total Commander has, so migration would be easier.
I hope you will consider implementing these features.
Thanks in advance!
