This is a reincarnation of a nice TotalCommander plugin (by Serge Lamikhov-Center) made for DoubleCommander users.

Update 1 Jul 2022: Now both GTK and Qt5!

requirements:

• libgtk2.0-dev (for gtk version)
• qtbase5-dev (for qt5 version)
• ELFIO (https://github.com/serge1/ELFIO) - downloads automatically

Attention: Qt5 version of this plugin does not work properly if the lister was started in "Preview" mode (key "0" to off/on). It doesn't receive PgUp/PgDown/Home/End/etc keyPress events, I dunno why =
Disable "Preview" mode or just tap "0" twice to reinitialize the lister window.
