I think it would be awesome if we could render and also interact with html and javascript in a terminal. The idea is to render buttons and other interactive widgets like file trees in the command line, and being able to interact with them with the mouse. It doesn't necessarily have to be built on html/js, but those technologies seem to fit the purpose and are probably the most advanced.
The advantage to a regular browser is of course that everything is still based on the terminal, so you have full control of the underlying system and can run commands directly. I rather imagine using commands like tree .
to show the current directory and subdirectories in an interactive tree widget you can expand with mouse clicks.
Are there any terminal emulators which support rendering of html pages and can run javascript?
