Thanks for sharing this. We have two option like filter actions with select and hover.
We also get some issue when we use the select action. Some time we can double click in icon then only it go back, i also changed as run on single click.
We will wait for new version.
I am having the exact same issue as you did, it seems right now no official solution to the "double click" shape navigation problem. if you use shape navigation filter action go from db1 to db2, and use another one go back to db1, you need click the shape once to unselect the mark, and click it again to switch to db2, which is a bad user experience.
there is a user who posted a solution, but not always work for all situations.
Tableau didn't design their worksheets with navigation in mind, so a selection requires you to unselect before moving on. I've been in discussions with them about altering the navigation, but I don't see this functionality changing any time soon.
Their provided solution is the Story function where you can place each dashboard as part of a slide show with navigation placed across the top. It works well if you only have a few dashboards, but more than 5 or 6 and it can get messy.
