I’ve been using SPE as my Python editor for a couple of years. It takes an IDE approach to the user window and UX model. I liked it, and I even donated money to its support fund.
But I’ve been an Emacs guy since back in the day. I was never fond of Emacs’ Windows integration, so I fell out of the habit of using it during my Windows years.
I’ve now discovered Aquamacs. Baby, I’m home.
