But the fullscreen dialogue should do no more than the current hover palette, there is no excuse for its code to being perceptibility slower. It's not starting up the activity or triggering an enema of module imports and dbus messages, it's just showing a full screen 'new or resume past instance' UI, with pretty much just the same content as the current 'weight and then fight with the cursor' mini palette. The down side is that every activity start would be then be two clicks, one to bring up the large dialogue (I like to think of it as a one page gallery), and one for new or resume choice... But that was partly the point, no one here could agree on a new or resume default behaviour, so there needs to be an extra user end decision, just to settle the UI feud and allow us move on, to more gainful tasks.
