it’s a merge of Midnight Commander and command line,
… because everything is panelized, greppable and remembered,
you enter commands like ls, mv, cp, cat and have their output captured, always,
then you can save the output via Ctrl-X (to a GDBM database) and visit it back with Ctrl-Shift-Left/Right,
the screen save includes complete state like: current working directory, grep keywords, cursor position, etc.
I’m hoping that it’ll gain some attention, because by accident I might have discovered a fully novel, unprecedented approach to file managers/command line.
