A cool feature for longer threads.

It'd be nice, if I double-clicked on the 'Preview-Screen', that I'd jump to that place in the 'Writing-Screen'.
Because I use the 'Preview-Screen' to 'scout' out what I've written before, what I write big, what small, if I have any 'plot-holes' in my texts and if I ever find a mistake, I have to scroll forever to get to that spot (in longer threads). So it'd be nice if double-clicking the 'Preview-Screen' would scroll the 'Writing-Screen' to that exact spot. Or the other way around, or maybe a button or something :)
