We have 2 projects with the proper boards displaying their workflows accurately. Project A has one board. Project B has three boards.
When i'm inside Project A i cannot see the boards from Project B and vice versa. I would like the 'boards' tab to show the boards from all projects so i can jump between them quickly.
The projects have very distinctive workflows.
When you create a Board, it will ask if you want to create a board based off of a pre-existing project or projects, select this option, and select all of the projects that you want to have represented in the Board.
You can use filter to only display tasks from projects that you want.

If what you want is to have visibility to multiple boards in one view, without having to change screens, I don't think Jira gives you this right of the bat. But you could try an add-on. Here is one I think does this.
