You know this would mean all generated screen content needs to be saved and maintained somewhere, right?

This would require vast more amounts of files and/or RAM to be used by Service Studio, to have every previously opened screen ready to be shown directly after you click it.
And even if this would get implemented, this requires a lot of development cost from the OutSystems team, as they need to change how ServiceStudio handles screen building (including a cache somehow, or having multiple screens open).

For some smaller screens, sure this could probably work. But as your application grows and screens increase in complexity, the amount of files generated/RAM needed would also increase.

I can see the possible decrease of the few seconds that you no longer need to wait for the screen to be redrawn.
But after webblock changes, all open screens that use the webblock need to be redrawn anyway. This could mean way longer wait-times to have all open screens refreshed.

I rather would like to have the screens being redrawn each time as it is right now, this way you have the current state of the page and the current state of the used webblocks.

I need to agree with Jeroen, how many times does one need to change all the screens. Doesn't make a lot of sense to me.

Agree with Jeroen and Daniel,

I rarely feel the need for multiple screens open at the same time.

It would maybe be nice to have more than just a single <arrow left> to get back to some screen i looked at before, but that's a different idea.

In the rare case where you want to have 2 screens open side by side for very intense comparing/copying, you could open the same module twice.

If it would be the standard that all screens stay open by default, it would be very annoying to constantly have to close the ones I'm no longer interested in.

Thanks for implemented this idea in latest service studio. 

I have same problem, so I wanna know how to display multiple screen.
Is ther any component I can use?
