How can I make single-pane as default layout?

I can't find the settings in which single-pane is the default layout, setting full pane width will be reset once I closed Multi Commander.

No it is not possible.

The whole design around this kind of file manager is that you have a source and target panel. And if you hide one of them by default it is to easy to mess things up because a lot of functions is assuming that it shown.

You can toggle the current panel to use full size with Ctrl+F11. But this settings is not saved between restarts.

Okay. But you might consider saving the ratio settings of the panes.
