From the developer:
FLTerm is a simple, small, scriptable terminal emulator, with unique features like command autocompletion, scp integration, batch automation, and scripting. The tool has a lightweight minimalist design and provides command history and auto-completion. It supports drag&drop text to run commands in batch and drag&drop files to transfer to remote host.
