I try to understand this new option "Unless open in other tabs".
I have 3 tabs open, folder tree of 1st tab is expand.
I click 2nd tab, only 2nd tab folder is expand. Strange
I click 3rd tab, all tabs folders are expand.
I click 1st tab again, only 1st tab folder is expand.
I miss something ?
I notice that check/uncheck option and apply this option in settings, change nothing until add another tab or open new Lister.
