Off the top of my head:
- The _block_ system where you could navigate up and down without scrolling the whole buffer rigidly - The tabbing system that actually works and doesn't feel clunky - The command prediction - The workflows (but that's now pretty much dead unless you really do not use AI)
The other thing I really love is the cross-platform support.
I don't have to tweak my usage of the terminal depending which platform I'm on.
I just have to remember to use Ctrl+Shift for copy/paste on Windows/Linux.
