In another file manager I used to use, when I got a focused (but not selected) file or folder and pressed ENTER it would treat it as if it was selected and run it / go inside that folder. But for safety, if I want to delete it I have to select if first.
And if it is the first time entering a folder, it would already put focus on the first file/folder.
I find this very useful. If you could implement it I would appreciate very much.
Thank you.
