Final Term is a powerful terminal emulator designed to give users a better experience with the command line. It is a modern, fully featured terminal application for Linux, macOS, and other Unix-like operating systems. It offers features like tabbed windows, drag-and-drop support, an intuitive search engine, and many other features that make it an ideal choice for those who want to work with the command line. Final Term is highly customizable and provides an easy-to-navigate interface that allows users to quickly perform various tasks. Final Term also includes features like syntax highlighting, auto-completion, and other tools that make it easier to work with the command line.
It is just one of many 'drop-down' style terminals that seem to be popular. It by no means has the same innovative thinking that the final term has.
