"Would be great to link between boards... so one card could lead to a whole to board
Basically lets say you're defining a major process of how you handle a new
custom from start to finish... one card could be around setting up proper
project structure.. if you clicked on that card it would open up another
board where that project structure is defined within another board.

This was you can easily jump between boards... through specific cards that
you would define." - Bart
