Thing is, it's not about the tools being sacred. My problem with this is that he's not just solving problems I don't have -- he's solving them in a way that would make my problems worse!
For instance, I very rarely want more informations about the files from an "ls" command; and if I did, I'd probably use Finder instead. On the other hand, not having enough terminal real estate to display the entire directory at once is a very frequent problem. From that perspective, adding icons is a step in the wrong direction.
Thinking about it, if I were playing with making a better terminal, one of my first lines of thought would be things that made it quick and easy to break information out into other windows, because scrolling back and forth in the terminal's buffer is a PITA.
Of course, this new terminal might be exactly what the author needs, and more power to him if it is. There's no need for us all to use the same tools. (Thanks heavens -- I want nothing to do with Emacs or vi!)
Regarding the too-small windows for ls output option I would love if his ls could display it's output full-screen temporarily rather than needing to make the terminal full-screen first and then running ls
See, here's the thing: I like Finder. It's not perfect, but sometimes it is very handy. Even if TermKit ends up implementing the complete functionality of Finder, I'm not sure why I'd particularly like to have that functionality in my terminal window. And if it's only implementing the one Finder view I virtually never use? Forget about it.
You know what would rock my world? A "lsf" command that emulated "ls" as much as possible, but launched a Finder window appropriately sized to display the results.
I've always thought Raskin's ZUI held some promise as an alternative UI paradigm. I'm pretty much a quicksilver addict now and use that to kind of combine the command line and GUI desktop worlds a little bit more at least.
