When using the Automatic Links feature, generated links currently always open in a new window (they have the HTML attribute target="_blank" set). However, some URL protocols are handled by locally installed applications instead of actually showing up in the browser window. For protocols like this, the user is left with an empty new browser window (or tab) that they have to manually close.
It would be nice to have an option when creating an Automatic Link for whether or not the generated link should open in a new window.
