I frequently have a bunch of tabs open. I tend to like having certain tabs in certain locations. E.g. the first three tabs are for tailing the three logs I'm most frequenly using. The rest may be ephemeral. Sometimes I either forget to start them in order or Ctrl+D out of one of them by mistake. Right now I resort to either closing the tabs or stopping and starting the require programs again in order. Reordering (either by dragging with the mouse or using a keyboard shortcut) would allow me to easily fix the mistake.
