I built this SSH file manager a while back that I've been using daily. Hoping others will find it useful too!

- Allows you to edit files like they were local.

- Automatically download and open files in any local editor (configurable).

- Automatically upload when changes are detected.

- Especially useful on slow and unstable links, where FUSE+SSHFS would cause too big of a slowdown on the local system.

- Edit files as root via sudo.

- Uses SSH auth agent when available, with fallback to password based authentication.

- Cross platform native GUI (via wxWidgets).
