Terminal and file manager, same app.
A real SFTP file manager with POSIX permissions, symlinks, search and bookmarks, sitting next to the terminal rather than in a second program — plus "terminal here" from any folder, and remote locations exposed to Explorer so other apps can open files off a server.
The TPM seals the vault key.
On a machine with TPM 2.0 the device vault key is generated in the chip and stays there, with your app password mixed in through Argon2id. Where there is no usable TPM the app says so plainly in its own security audit rather than reporting a hardware key it does not have.
Upgrades that keep your setup.
The .msix installs and upgrades in place, carrying your vault, servers, keys and settings across versions. Storage is one SQLCipher database rather than a scattering of config files, so there is a single thing to back up and a single thing to migrate.
No WSL, no bundled browser.
The SSH, Mosh and Eternal Terminal clients are native C and C++ reached over FFI, and the terminal is parsed by libvterm and drawn by our own renderer. Nothing here shells out to WSL or ships a copy of Chromium to paint text.
