It even still uses the same hotkeys as Norton Commander. Still, it supports Total Commander's plugins in case someone is using those, it's LGPL, it looks like a decent example of a useable Free Pascal application to dive into contributing against, it's cross-platform (Windows, Linux, FreeBSD, macOS), and it builds against gtk2, qt4, or qt5. Overall it looks like a nice project. It could probably use a commit in the About page for a first contribution to the project noting a little more history of its lineage.
