i'd like the option, in the preview window options, to 'switch previewed layer on next layer change'. that way i could do with a single preview window.
at the moment, i got chortcuts assigned to the up and down buttons in the layer control of the media bin. also i got 'switch layer tabs on next layer change' in the media bin options checked. and 'switch layers with layer tabs' in the layer controls plugin checked.
this works very nice, using two universal shortcut keys (up and down key) both for viewing whats going on everywhere, and deciding where to trigger next.
the only thing missing would be for the preview window to change along with the other
