The best journey maps are build collaboratively. And it's not just UX designers that should be involved in the process of journey mapping - you should invite people from across all departments.
For that reason we build UXPressia in a way that let you work on your maps and personas in real time from multiple accounts simultaneously. All changes made by your teammates are visible to everyone, the team is synced and everybody's happy.
It also allows you to work from different browser tabs, if necessary.
p.s. tiles with names won't be visible and are on the GIF just for visualization. :)
