Oy, tool idea:
2 keyboard shortcuts:
One to mark, remember a certain position, line / pattern-number.
One to goto, jump to that marked position.
Lets say you have a point of interest in your composition 
/> , for example start of a 4 pattern chorus. You press the shortcut to mark it, proceed to work on the other patterns and when ready, jump to the remembered position to play the complete section.
Could be handy imo when working for a bit on sections that need playback from a certain point.
