Please add a 'last edited' column to the xtools utility "articleinfo", in order to help determine which users are good candidates to be pinged to a discussion at the article's Talk page. Pinging editors who haven't edited in a year is a waste of time, but clicking through the users to find that info currently takes a lot of clicks with a low success rate.

A new date column in the tables in the Top editors section containing the date of the editor's last contribution to Wikipedia would make this a lot easier.

Even better: a font-height sparkline showing their contribution pattern of the last 6 months or so, if any, plus last-edit date. Knowing they edited once ten days ago is good; knowing that it was part of a steady pattern, rather than their first time back in a year is better. (If a sparkline is too hard, then last edit, plus sthg like, "mean time between edits in last 6 months" or similar.) But even just last edit would be a big improvement.
