I actually like my shell as it is. I like the old fashion with no mouse interaction except for scrolling. Is it just me? But I have to say the interactive search is appealing.
My approach to CLI is basically: if I wanted to use the mouse, I wouldn't be in the terminal. Having to reach for the mouse is a huge waste of time and I only do it if I need to scroll (rare) or copy+paste (relatively common).
Although since I use OS X (Darwin) I don't always need the mouse to copy+paste (ie. pbcopy -> cmd+V).
