As a fellow iterm2 refuge, here's my config:

I added back the familiar option/cmd + arrow key navigation and cmd + click hyperlink behaviour.

There's also some tweaking to make it more similar to iterm's default behaviours (e.g. don't hide the mouse when you start typing).

And finally some personal visual tweaks which you can throw out and replace with your own.
