I would like a button to switch visibility of a chunk on and off. I can see the chunk I am on, or all aligned, but it would be more useful to be able to see all aligned chunks and then switch chunks on and off.
Also if you add manual alignment of chunks, an opacity control would be helpful too.
A completely unrelated request- Would it be possible to allow the output view to be scrolled during processing? Perhaps by breaking it into a separate window or writing to a log file? Also timestamps with the events.
