I'm editing a few redirects on my account and here's a suggestion that would make it easier.
From the Redirects page I press delete, wait for a page load, then confirm, wait for a page to load and I get pushed back to the Summary page. It would be better if I was pushed to the Redirects page, where I came from.
It would save me a click and page load.
What would really save me time is if there were check boxes and a button to do mass deletes of redirects - obviously with a confirmation screen to avoid click happy moments.
