Be able to pin the summary box open from project to project

In the new WF Experience you have a very handy summary box on the right of the tasks. It's a useful box that some of my users like to use BUT it closes itself when moving from project to project.

Can we have a 'Pin sidebar' option on the top of that sidebar and have that user's browser remember if it is open or closed please?

Right now it is a good feature that we rarely use just because it keeps closing itself.

Thanks

Chris
