I am working on a very long workflow with multiple milestones.
It would be a great feature if you could collapse and expand milestones (leaving the titles of the swimlanes) so that you could get a better view of who is assigned to what, and to have the ability to focus in on a specific milestone.
I imagine being able to right click on the milestone title and select "collapse milestone" or "expand milestone" from a pop up menu.
p.s. I am really impressed with Bizagi!
