Eugeny/tabby — reverse-engineered prompt

Build me a modern desktop terminal app for Windows, macOS, and Linux that feels nicer than the default terminal or PuTTY. I want tabs, split panes, saved sessions, remembered tabs after restart, custom themes, color schemes, fonts, and editable keyboard shortcuts.

It should handle local shells like PowerShell, WSL, Git Bash, CMD, and normal Mac or Linux shells, plus built in SSH, Telnet, and serial connections. For SSH, let people save hosts, use an encrypted place for keys and secrets, do port forwarding, jump hosts, agent forwarding, login scripts, and simple file transfer during a session. For serial, support saved devices, reconnecting, newline options, and a readable hex view.

Please make the terminal solid with Unicode support, fast output, copy on select, paste warnings, notifications when commands finish, and a settings screen where users can install or switch themes and plugins. Look up current docs online if you need to.
