Two panes. Ten F-keys. Any server.

Total Commander manners, macOS habits.

• Two panes, many tabs Each tab keeps its own path, history, selection, sorting, and its own server connection. ⌘T opens one, ⌃Tab cycles them.
• The classic keyboard F3 view, F4 edit, F5 copy, F6 move, F7 new folder, F8 delete, F9 terminal, plus ⌥F1/⌥F2 for the drive list, exactly where thirty years of muscle memory expect it.
• Servers as first-class panes SFTP with password or OpenSSH key, FTP and FTPS in either pane. Search, checksums, and the viewer all work over the connection too.
• Trust done right SSH host keys are checked against your own ~/.ssh/known_hosts, hashed entries included, and a changed key is refused outright, never prompted away.
• Zip as a folder Enter walks into an archive and F5 copies out of it; ⌥F5 packs, ⌥F9 unpacks. The ZIP engine is written by hand on Apple's public Compression framework.
• Find, compare, verify Recursive search with commander-style masks, directory compare, content compare with a patience diff, and checksum files that md5sum and shasum accept verbatim.

F3 went a little further than it had to.

• Text and hex, remembered A reader on F3, an editor on F4, legacy encodings detected, and a cursor that returns to where you left every file, even after a restart.
• Rendered documents Markdown with images, PDF, SVG kept as vectors, and every bitmap format the system knows. All loaded through the pane's own provider, so remote files preview like local ones.
• A real disassembler ⌘D in the hex view decodes ARM64 and x86 via Capstone, seeded by reading just enough Mach-O to find the code.
• 3D models FBX files, in the text or the binary flavour, get parsed, triangulated, textured, and put on a turntable. No engine, no import library.

Built by hand, on purpose.

The interesting parts are not wrappers. The ZIP reader and writer are implemented against the raw format (data descriptors, zip64, and a zip-slip guard included), because every shortcut macOS offers turned out to have a hole in it. The FBX parser, the patience diff, the single-pass syntax highlighter, and the coreutils-compatible checksum escaping are the same story: small, verified implementations instead of dependencies. The app is fully sandboxed, ships a privacy manifest, and phones nobody.
